Question

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

Answer 1

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

Answer 2

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.

$7 \times 7 \times 7 \times 7 \times 7 = {7}^{5}$
${7}^{8} - {7}^{3} = {7}^{5}$
${7}^{5} \times {7}^{1} = {7}^{6}$
