Question

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

Answer 1

 (4 elevado 3-x)elevado 2-x = 1

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

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

2x²  - 10x + 12 = 0

Δ = 100 - 4.(2).12 = 100 - 96 = 4

x = 10+/-2  ==> x = 10 +/-2
         2.2                      4

x1 =  3   ; x2 = 2
