Question

(7^3) *7^7
__________
(7^5)^4
​

Answer 1

$\frac{ {7}^{3} \times {7}^{7} }{ {( {7}^{5}) }^{4} } = \frac{ {7}^{10} }{ {7}^{20} } = \frac{1}{ {7}^{10} } = {7}^{ - 10}$

Answer 2

$\frac{( {7}^{3}) \times {7}^{7} }{ {( {7}^{5} )}^{4} } = \frac{ {7}^{3 + 7} }{ {7}^{5 \times 4} } = \frac{ {7}^{10} }{ {7}^{20} } = \frac{ 1}{ {7}^{10} }$
