Question

3 raised to what power is equal to 81? (1 point)

Explanation:

Step1: Define the unknown exponent

Let the unknown power be $x$. The equation is $3^x = 81$.

Step2: Rewrite 81 as power of 3

Note that $81 = 3 \times 3 \times 3 \times 3 = 3^4$.

Step3: Equate exponents (same base)

Since $3^x = 3^4$, $x=4$.

Answer:

4
