Question 189991: Solve each equation.() means that number is the base number

8 – 3^x = –1

log(3)81 = x

log x – log 3 = 2

You can put this solution on YOUR website!
8 – 3^x = –1
3^x = 9
3^x = 3^2
x = 2
------------------
log(3)81 = x
3^x = 81
3^x = 3^4
x = 4
-------------------
log x – log 3 = 2
log(x/3) = 2
x/3 = 10^2
x/3 = 100
x = 300
