Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: QUESTION \: \: } \mid}}}}}$

$\: \: \: \: \mathtt{Find \: \: the \: \: value \: \: of \: \: the \: \: following :- } \\ \\ \: \: \: \: \: \: \: \: \mathtt{(a) \: \: 5 {}^{ - 3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (b)( - 3) {}^{5} }$

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: ANSWER \: \: } \mid}}}}}$

$\tt{(a) \: 5 {}^{ - 3} } \\ \\ \tt{ = \frac{1}{5 {}^{3} } } \\ \\ \tt{ = \frac{1}{125} } \\ \\ \tt{ = 0.008}$

$\tt{(b) \: ( - 3) {}^{5} } \\ \\ \tt{ = ( - 3) {}^{3} \times ( - 3) {}^{2} } \\ \\ \tt{ = ( - 3) \times ( - 3) \times ( -3 ) \times ( - 3) {}^{2} } \\ \\ \tt{ = (- 27) \times 9} \\ \\ \tt{ = - 243}$

FORMULA USED :-

$\tt{1. \: \: a {}^{ - m} = \frac{1}{a {}^{m} } } \\ \\ \tt{2. \: \: a {}^{m} \times a {}^{n} = a {}^{m + n} }$
