The correct Answer is:
To solve the equation \( \frac{3^{15} \times 9^{22}}{27} = 3^{?} \), we will first express all the terms in the equation using the base 3. ### Step 1: Rewrite \( 9^{22} \) and \( 27 \) in terms of base 3. - We know that \( 9 = 3^2 \), so: \[ 9^{22} = (3^2)^{22} = 3^{2 \times 22} = 3^{44} \] - We also know that \( 27 = 3^3 \). ### Step 2: Substitute these values back into the equation. Now we can rewrite the equation as: \[ \frac{3^{15} \times 3^{44}}{3^3} = 3^{?} \] ### Step 3: Combine the powers of 3 in the numerator. Using the property of exponents that states \( a^m \times a^n = a^{m+n} \): \[ 3^{15 + 44} = 3^{59} \] So now our equation looks like: \[ \frac{3^{59}}{3^3} = 3^{?} \] ### Step 4: Simplify the left side using the property of exponents. Using the property \( \frac{a^m}{a^n} = a^{m-n} \): \[ 3^{59 - 3} = 3^{?} \] This simplifies to: \[ 3^{56} = 3^{?} \] ### Step 5: Set the exponents equal to each other. Since the bases are the same, we can equate the exponents: \[ ? = 56 \] Thus, the value that should come in place of the question mark is: \[ \boxed{56} \]
