Question

Solve for x:
3^3 * 3^x * 3^x-1= 3^12
do you just combine alike exponents??

Answer 1

when multiplying the same bases, you add the exponents:
3^3 * 3^x * 3^(x-1)= 3^12
3^(3+x+x-1)=3^12
thus
3+x+x-1=12
x+x=12-3+1
2x=13-3
2x=10
x=5

Answer 2

thank you, how about if the bases were differeent?
