What exponent would make the two expressions equivalent: (3^3)^x = 3^24?

A)15
B) 27
C)8
D)21

1 answer

To solve the equation \((3^3)^x = 3^{24}\), we can use the property of exponents that states \((a^m)^n = a^{m \cdot n}\). Thus, we can rewrite the left side of the equation as follows:

\[ (3^3)^x = 3^{3x} \]

Now we have the equation:

\[ 3^{3x} = 3^{24} \]

Since the bases are the same, we can set the exponents equal to each other:

\[ 3x = 24 \]

Now, we can solve for \(x\) by dividing both sides by 3:

\[ x = \frac{24}{3} = 8 \]

Thus, the exponent that makes the two expressions equivalent is:

\[ \boxed{8} \]
