What is a single power in math? The power (or exponent) of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number.
How do you multiply powers?
Rules for Multiplying Exponents with Variables
- When the variable bases are the same, the powers are added.
- When the variable bases are different and the powers are the same, the bases are multiplied first.
- When the variable bases and the powers are different, the exponents are evaluated separately and then multiplied.
What is a single power?
What is a single power of 2? In mathematics, a power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent. Written in binary, a power of two always has the form 100…000 or 0.00… 001, just like a power of ten in the decimal system.

0:022:33So part one we've got twenty five the power of four. And we want to make that as a power of five.MoreSo part one we've got twenty five the power of four. And we want to make that as a power of five. Well first of all we can rewrite 25. As 5 squared. That's 25 25 to the power 4.
What is a single power in exponents?
Power of a power The result is a single exponential where the power is the product of the original exponents: (xa)b=xab. We can see this result by writing it as a product where the xa is repeated b times: (xa)b=xa×xa×⋯×xa⏟b times. Next we apply rule (1) for the product of exponentials with the same base.
What is a single power of 10?
A power of 10 is as many number 10s as indicated by the exponent multiplied together. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.
How do you express as a single power of 2?
1:496:32The next example is 2 raised to 1 minus n raised to minus 1.. Now here again we could multiply theseMoreThe next example is 2 raised to 1 minus n raised to minus 1.. Now here again we could multiply these two terms so you have 2 raised to minus 1 into 1 minus n let us open up the brackets.
How do you get rid of a 1/2 exponent?
0:021:40Times 2 okay a to the 6 B to the 5th C squared. And I did that so square root of 25 is just 5 andMoreTimes 2 okay a to the 6 B to the 5th C squared. And I did that so square root of 25 is just 5 and notice there 2 is going to be left behind inside the square root. Okay now the index here is 2.
How do you rewrite with a single positive exponent?
0:052:30We take the exponent. And make it positive. So X to the negative 5 is really the same as 1 over X toMoreWe take the exponent. And make it positive. So X to the negative 5 is really the same as 1 over X to the 5.
How do you write 8 as a power of 2?
so 82 = 8 × 8 = 64 Exponents are also called Powers or Indices.
What is 5 by the power of 5?

What is 8 by the power of 3?
Answer: 8 to the power of 3 can be expressed as 83 = 8 × 8 × 8 = 512.
What is power in math?
The Interesting World of Mathematics Power Calculator. Mathematics power, or simply exponent, is the method of multiplying a number by itself. The number in the exponential portion is the number of times you'll need to multiply the number.
What does raising the power of a product do?
Raising the power of a product increases the powers of the involved numbers by the same power.
What is an exponential function?
In its textbook definition, an exponential function is a number with a positive real number in the superscript where the number in the exponential form equals how many times the real number must be multiplied by itself.
Power and roots
Squares, cubes and higher powers are shown as small digits called indices. The opposite of squaring and cubing are called square root and cube root. There are more rules we can use with indices.
Index form
The notation 3 2 and 2 3 is known as index form. The small digit is called the index number or power.
What does the power of a number mean?
It is important to recall some basic information about the powers of the numbers. To begin with, a power shows how many times a number is multiplied by itself. For example, if we take a number 2 raised to the power of 2, or squared, (written like this - 2^2) then we get an answer of 4. This is because 2 x 2 = 4. So we have multiplied 2 by itself twice. The numbers can be raised up to infinity. However, there are some very important rules that should be remembered.
What is the name of the number raised to powers?
Secondly, the numbers raised to powers are known in mathematics as exponentials and all have exponential function graphs, either the exponential growth one or the exponential decay one. Thus, we need to recall some basic rules.
What happens when a number is raised to a negative power?
If a number is raised to a negative power, then it will be rewritten as 1 divided by that number raised to the power, e.g. 2^-2 = 1/2^2
Can numbers be raised to infinity?
The numbers can raised up to infinity. However, there are some very important rules that should be remembered. Firstly, a reverse operation of powers would be the roots. If we take the same example of 2, being raised to the power of 2 which equals to 4, we can square-root 4 (√4) and it equals to 2. Nevertheless, as mentioned earlier, ...
