Answer 1

$\Huge\bf{\blue{\blacksquare \: Answer:}}$

_____________________________

(d) $\Large(\frac{1}{2})^{-4}$

$\Large=(\frac{2}{1})^4$

$\Large=(2)^4$

$=\fbox{16}$

(e) $\Large(\frac{2}{3})^{-5}$

$\Large=(\frac{3}{2})^5$

$=\fbox{\frac{243}{32}}$

(f) $\Large(\frac{-3}{5})^{-2}$

$\Large=(-\frac{5}{3})^2$

$=\fbox{\frac{25}{9}}$

(g) $\Large(\frac{3}{-7})^{-3}$

$\Large=(\frac{-7}{3})^3$

$=\fbox{\frac{343}{27}}$

(h) $\Large(\frac{-3}{4})^{-4}$

$\Large=(\frac{4}{3})^4$

$=\fbox{\frac{256}{81}}$

(i) $\Large(\frac{2}{5})^{-3}×(\frac{2}{3})^{-2}$

$\Large=(\frac{5}{2})^3×(\frac{3}{2})^2$

$\Large=(\frac{125}{8})×(\frac{27}{8})$

$=\fbox{\frac{3375}{64}}$

(j) $\Large(\frac{-1}{4})^{-3}÷(\frac{3}{8})^{-2}$

$\Large=(\frac{4}{-1})^3÷(\frac{8}{3})^2$

$\Large=(\frac{64}{1})÷(\frac{64}{9})$

$\Large=(\frac{64}{1})×(\frac{9}{64})$

$\large=\fbox{9}$
