What is the rule when multiplying exponents?

Multiplying Exponents with the Same Base. When we multiply two expressions with the same base, we apply the rule, a m × a n = a (m + n), in which 'a' is the common base and 'm' and 'n' are the exponents. For example, let us multiply 2 2 × 2 3. Using the rule, 2 2 × 2 3 = 2 (2 + 3) = 2 5. Multiplying Exponents with Different Base and Same Power

What do you do when multiplying exponents?

When multiplying exponents, if the exponents are positive, you add them together. If the exponents are negative, you subtract. The rules are the same as adding and subtracting integers. However, you can only combine exponents if the base is the same (i.e., 2^4 and 2^7 multiplied 2^4 * 2^7 = 2^11).

What is the difference between a base and an exponent?

Exponents, often known as powers, are numbers that indicate how many times a base number may be multiplied by itself. For instance, the number 43 instructs you to multiply four by itself three times. The base is the number being raised by a power, whereas the exponent or power is the superscript number above it.

How to prove exponents?

The exponent rules can be proved easily by expanding the terms. The exponential expression is expanded by writing the base as many times as the power value. The exponent of the form a n is written as a × a × a × a × a × .... n times. Further, on multiplying we can obtain the final value of the exponent. For example, let us solve 4 2 × 4 4. Using the 'product law' of exponents, which says a m × a n = a m+n, we get 4 2 × 4 4 = 4 2 + 4 = 4 6. This can be expanded and checked as (4 × 4) × (4 × 4 × 4 × 4) = 4096. We know that the value of 4 6 is also 4096. Hence, the exponent rules can be proved by expanding the given terms.

What are Exponents?

Exponents are used to show repeated multiplication of a number by itself. For example, 7 × 7 × 7 can be represented as 73. Here, the exponent is ‘3’ which stands for the number of times the number 7 is multiplied. 7 is the base here which is the actual number that is getting multiplied. So basically exponents or powers denotes the number of times a number can be multiplied. If the power is 2, that means the base number is multiplied two times with itself. Some of the examples are:

What is the exponent of the answer?

The exponent of the answer is the product of the exponents: (x2)3 =x2⋅3 = x6 ( x 2) 3 = x 2 ⋅ 3 = x 6. In other words, when raising an exponential expression to a power, we write the result with the common base and the product of the exponents.

What is the exponent of a product?

Notice that the exponent of the product is the sum of the exponents of the terms. In other words, when multiplying exponential expressions with the same base, we write the result with the common base and add the exponents. This is the product rule of exponents.

We can always check that this is true by simplifying each exponential expression. We find that 23 2 3 is 8, 24 2 4 is 16, and 27 2 7 is 128. The product 8⋅16 8 ⋅ 16 equals 128, so the relationship is true. We can use the product rule of exponents to simplify expressions that are a product of two numbers or expressions with the same base but different exponents.
