Answer 1

(3/5)² = (3/5)(3/5) = 9/25
(-4/7)² = (-4/7)(-4/7) = 16/49
(-1/5)³ = (-1/5)(-1/5)(-1/5) = -1/125
(-1/2)^4 = (-1/2)(-1/2)(-1/2)(-1/2) = 1/16
(1/3)^5 = (1/3)(1/3)(1/3)(1/3)(1/3) = 1/243
3²/2 = 9/2

Answer 2

.
$a)~~~~( \frac{3}{5} )^2= \frac{9}{25} \\ \\ b)~~~(- \frac{4}{7} )^2=+ \frac{16}{49} \\ \\ c)~~~(- \frac{1}{5} )^3=- \frac{1}{125} \\ \\ d)~~~(- \frac{1}{2} )^4=+ \frac{1}{16} \\ \\ e)~~~(+ \frac{1}{3} )^5=+ \frac{1}{243} \\ \\ f)~~ \frac{3^2}{2} = \frac{9}{2}$
