Question

(5raise to 2)raise to 1 divided by 2

Answer 1

Answer:

40

Step-by-step explanation:

Given phrase,

2 raise to power minus 1 into 5 raise to power minus 1 whole raise to power minus 1 divided by 4 raised to power minus 1​,

\implies \frac{(2^{-1}\times 5^{-1})^{-1}}{4^{-1}}

=\frac{(2^{-1})^{-1} \times (5^{-1})^{-1}}{4^{-1}}  (\because (ab)^m=a^m.b^m)

=\frac{2^{-1\times -1}\times 5^{-1\times -1}}{4^{-1}}   (\because (a^n)^m=a^{nm})

=\frac{2\times 5}{4^{-1}}    (\because \frac{1}{a^m}=a^{-m})

=10\times 4

=40

Answer 2

Answer:

(5^2)1/2
