To find the exponent that would make the two expressions equivalent, we need to solve the equation (33)x = 324.
By taking the logarithm of both sides, we can determine the value of x:
log((33)x) = log(324)
Using logarithmic properties, we can bring down the exponent and rewrite the equation as:
x * log(33) = log(324)
Now, we can solve for x:
x = log(324) / log(33)
Using a calculator, we can evaluate the logarithms and find that:
x ≈ 2.079
So, the exponent that would make the two expressions equivalent is approximately 2.079.
