Question

Find the value of x.
log 3 x = 4

Answer 1

81

Explanation:

We can solve for x by first using the definition of logarithms, which states that log base a of b is equal to c if and only if a raised to the power of c equals b.

Using this definition, we can rewrite the given equation as:

3^4 = x

Simplifying this expression, we get:

81 = x

Therefore, the value of x is 81.
