Answer 2

(vii)

$Given : \frac{(27)^{-\frac{2}{3}} * 81^{\frac{5}{4}}}{(\frac{1}{3})^{-3} }$

$=>\frac{(3^3)^{-\frac{2}{3}} * (3^4)^{\frac{5}{4}}}{3^3}$

$=>\frac{3^{-2} * 3^5}{3^3}$

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

$=> 1$

(viii)

$Given : (64)^{\frac{1}{2}}(64^{\frac{1}{2}} + 1)$

$=> \sqrt{64}(\sqrt{64} + 1)$

$=>8(8 + 1)$

$=>8*9$

$=>72$

Hope it helps!
