Question

Which of the following expressions is equivalent to the one shown below?

713
7⁰
OA. 720
OB. 75
O C. 76
O D. 791

Answer 1

(A^m)/(A^n) = A ^ (m-n).
(7^13)/(7^7) = 7 ^(13-7),
7^(6) = 117649

Answer 2

Answer: Option C
`\boldsymbol{7^6}`

Work Shown:

`(7^(13))/(7^(7))\\\\\\7^(13-7)\\\\\\\boldsymbol{7^6}`

Subtract the exponents to get the answer. The rule is
`(a^(b))/(a^(c)) = a^(b-c)`. This rule only works when the bases are the same.
