Question

Which expressions are equivalent to 7•7•7•7•7?

Choose all answers that apply

A. 7^8/7^3
B. 7^5 • 7^1
C. All of the above

Answer 1

The answer to this question is A. This is explained by a common trick that when you divide two terms with exponents, you subtract the second exponent from the first. When multiplying, you add the exponents.


`7 * 7 * 7 * 7 * 7 = {7}^(5)`

`{7}^(8) - {7}^(3) = {7}^(5)`

`{7}^(5) * {7}^(1) = {7}^(6)`

Answer 2

It's just AAAAA, no other answers. So just check A
