Question

Solve for x if 25^x+2=125^3x+4

Answer 1

This one was pretty tough but Math way helped, you should try it out, it explains the problems so you can learn it. I got x = 0, 5

Answer 2

What you want to do is write the numbers with similar bases, and then you can cross the bases off. Like this:

25^x+2=125^3x+4
5^2(x+2)=5^3(3x+4)
Now you can cross the similar bases off.
2(x+2)=3(3x+4)
2x+4=9x+12
7x=-8
X=-8/7
