c) 2x+6=4x+2
6-2=4x-2x
4=2x
x=4:2=2
b)5x+2=32
5x=30
x=30:5
x=6
[tex](10^x)^5*100=(2^4*5^4)^8\\10^{5x}*10^2=(10^4)^8\\10^{5x+2}=10^{32}\\10^{5x}=10^{32-2}\\10^{5x}=10^{30}\\5x=30\\x=\frac{30}{5} =6[/tex]

[tex](5^2)^{x+3}=5^{4x}*5^2\\5^{2(x+3)}=5^{4x+2}\\5^{2x+6}=5^{4x+2}\\2x+6=4x+2\\2x-4x=2-6\\-2x=-4/*(-1)\\2x=4\\x=\frac{4}{2} =2[/tex]
