2^2 x 2^?=2^13

1 answer

To solve the equation \(2^2 \times 2^? = 2^{13}\), we can use the properties of exponents. Specifically, when multiplying two exponential terms with the same base, we can add their exponents:

\[ 2^2 \times 2^? = 2^{2 + ?} \]

So we can rewrite the equation as:

\[ 2^{2 + ?} = 2^{13} \]

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

\[ 2 + ? = 13 \]

Now, we solve for \( ? \):

\[ ? = 13 - 2 = 11 \]

Thus, the value of \( ? \) is \( \boxed{11} \).
