The correct Answer is:
To solve the equation \(\frac{x^2}{128} = \frac{32}{x^{10}}\), we will follow these steps: ### Step 1: Set the equation Let the question mark be represented by \(x\). Therefore, we can rewrite the equation as: \[ \frac{x^2}{128} = \frac{32}{x^{10}} \] ### Step 2: Cross-multiply To eliminate the fractions, we will cross-multiply: \[ x^2 \cdot x^{10} = 32 \cdot 128 \] ### Step 3: Simplify the left side Using the properties of exponents, we can simplify the left side: \[ x^{2 + 10} = 32 \cdot 128 \] This simplifies to: \[ x^{12} = 32 \cdot 128 \] ### Step 4: Calculate the right side Now, we need to calculate \(32 \cdot 128\). We can express these numbers as powers of 2: \[ 32 = 2^5 \quad \text{and} \quad 128 = 2^7 \] Thus: \[ 32 \cdot 128 = 2^5 \cdot 2^7 = 2^{5 + 7} = 2^{12} \] ### Step 5: Set the exponents equal Now we have: \[ x^{12} = 2^{12} \] ### Step 6: Solve for \(x\) Since the bases are the same, we can set the exponents equal to each other: \[ x = 2 \] ### Conclusion The value that will come in place of both question marks is: \[ \boxed{2} \] ---
