Answer:
4
Explanation:
3^x =64
Take the logarithm of both sides of the equation.
log(3^x)=log(64)
The logarithm of a number raised to a power is the power times the logarithm of the number.
xlog(3)=log(64)
Divide both sides by log(3).
x=Log(64)/LOG(3)
You need a calculator for this part.
x = 3.78557852143, which rounded to the nearest whole number is 4.
