Question

Express the number in exponential form
(1) 64/343
(2) -27/125

Answer 1

Solution :

$(1) \: \: \frac{64}{343}$

$= > \frac{ {4}^{3} }{ {7}^{3} }$

$= > ( \frac{4}{7} ) ^{3} .$

$\: \: \: \: \: (2) \: \: \: \frac{ - 27}{125}$

$\: \: \: \: \: = > \frac{ { (- 3)}^{3} }{ {5}^{3} }$

$\: \: \: \: \: = > ( \frac{- 3 }{5} ) ^{3} .$
