Tentukan perkalian Dari Nilai x yang Memenuhi x log (5X³-4X)=x log xPangkat 5

jawab

ˣlog (5x³ - 4x) = ˣlog x⁵
5x³ - 4x = x⁵ , pembatas x > 0
x⁵ - 5x³ + 4x = 0
x (x⁴ - 5x²  +4) = 0
x (x² - 4)(x² - 1)  = 0
x(x-2)(x+2)(x-1)(x+1)= 0
x = 0, x = 2 , x = - 2 , x = 1 , x = -1
x> 0
x = 2 , x = 1
hasil kali = 2(1) = 2
