Tolong bantuin ya.... S.O.S

Answer 1

Gunakan sifat eksponen :
a^m x a^n = a^(m+n)
a^(-m) = 1 / a^m

a) 7^(2/3) x 7^(1/2) = 7^(2/3 + 1/2) =  7^(7/6)
b) 4^(-1/2) x 4^(3/2) = 4^(-1/2 + 3/2) = 4
c) (-5) x (-5)^(2/3) = (-5)^(1 + 2/3) = (-5)^(5/3)
d) 8^(-1/4) x 2^(-3/2) = (2^3)^(-1/4) x (2^(-3/2) = 2^(-3/4) x 2^(-3/2) = 2^(-3/4 - 3/2) = 2^(-9/4) = 1 / (2^(9/4)
