(4 elevado 3-x)elevado 2-x = 1

Answer 1

 (4 elevado 3-x)elevado 2-x = 1

4(^3-x)^2-x = 4^0  ==> 4^(3-x)(2-x) = 4^0

(3-x)(2-x) = 0 ==> 6-3x-2x + x^2 = 0 ==> 6 - 5x + x^2 = 0

x²  - 5x + 6 = 0

Δ = 5² - 4.1.6 = 25 - 24 = 1

x = 5+/-1  ==> x = 5+/-1
         2.1                   2

x1 =  3   ; x2 = 2
