Bonsoir,

(3/2)⁴ = 3⁴/2⁴ = 81/16

((-2)/6)² = (-1/3)² = (-1)²/3² =  1/9

Bonsoir

a) [tex](\frac{3}{2}) ^{4}[/tex] = [tex]\frac{3^{4} }{2^{4} }[/tex] = [tex]\frac{81}{16}[/tex]

b) [tex](\frac{-2}{6}) ^{2}[/tex] = [tex](\frac{-1}{3}) ^{2}[/tex] = [tex]\frac{(-1)^{2} }{3^{2} }[/tex] = [tex]\frac{1}{9}[/tex]
