Question

what is the answer of this question(-1/2) ^-2 =?
​

Answer 1

Answer:

4

Step-by-step explanation:

$\frac{( - 1)}{ ( 2)} ^{ - 2}$

${a}^{ - 2} = \frac{1}{ {a}^{2} }$

$\frac {(2 \: )}{ (- 1)} ^{2} \\ \\ (- 2) ^{2} = - 2 \times - 2 = 4$

in multiplication of two negative integers gives us positive integer

Answer 2

Answer:

${ (\frac{ - 1}{2} )}^{ - 2} \\ = \frac{1}{ {( \frac {- 1}{2}) }^{2} } \\ = { (\frac{2}{ - 1}) }^{2} \\ = \frac{4}{1} \\ = \large{ \boxed{ \bf{ \underline{ \underline{4}}}}}$
