Вариант 4.
1) 2^1-х=8=2³ =>1-х=3, х=-2
2)2^4х-19=⅛= 2^-3 => 4х-19=-3, х=4
3)(¼)^4х-10=1/16=4^-2 =>4^-4х+10=4^-2 => -4х+10=-2, х=3
4)1/5^5-х=25=5² => 5^х-5=5² =>х-5=2, х=7
5)32^х-3=½ => 2^5х-15=2^-1 => 5х-15=-1, х=2,8
6)6^6+х=216=6³ => 6^6+х=6³ => 6+х=3, х=-3
7)(½)^х-5=8^х => 2^5-х=2^3х => 5-х=3х, х=1,25
8)(1/36)^х-8=6¹ => 6^16-2х=6¹ => 16-2х=1, х=7,5
9)(⅛)^4+х=64 => 8^-х-4=8² => -х-4=2, х=-6
10)7^3-2х=49^2х => 7^3-2х=7^4х => 3-2х=4х, х=0,5
