Answer 2

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​,

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

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

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

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

$=10\times 4$

$=40$
