Answer 1

4^(4-x)=1/16
4^(4-x)=(1/4)²
4^(4-x)=4⁻²
4-x=-2
x=6

(1/5)^(2-4x)=∛5
(1/5)^(2-4x)=5¹/³
(1/5)^(2-4x)=(1/5)⁻¹/³
2-4x=-1/3
-4x=-1/3-2
x=(-7/3):(-4)
x=7/12

Answer 2

4^(4-х)=1/16
4^(4-х)=4^(-2)
4-х=-2
х=4+2
х=6


(1/5)^(2-4х)=куб!/5
(1/5)^(2-4х)=5^(1/3)
(1/5)^(2-4х)=(1/5)^(-1/3)
2-4х=-1/3
4х=2+1/3
4х=2 1/3
х=7/3×1/4
х=7/12

4^(-3х-4)=4
-3х-4=1
-3х=5
х=-5/3=-1 2/3
