Question

simplify 8^5/8^7 the question
​

Answer 1

Here the numbers are dividing so we subtract the powers 5 - 7 that is -2 so the answer would be 8^-2 but simplifying we get 1/8 raised to power 2 so solution is 1/64

Answer 2

Question :-

$\frac{8 {}^{5} }{8 {}^{7} }$

Solution :-

Apply formula

$( \frac{x {}^{m} }{x {}^{ n} } ) = (x {}^{m - n} )$

Hence,

$( \frac{8 {}^{5} }{8 {}^{7} } ) = (8 {}^{5 - 7} ) = (8 {}^{ - 2} ) \\ \\ = \frac{1}{8 {}^{2} } = \frac{1}{64} \: \: \: \: ans$
