The correct Answer is:
To solve the equation given in the question, we will follow these steps: ### Step 1: Write down the equation The equation we need to solve is: \[ \frac{144.01}{\sqrt[4]{?}} + 24.03\% \text{ of } 124.97 = (8.01)^2 - \sqrt{99.99} \] ### Step 2: Approximate the values We will approximate the values: - \(144.01 \approx 144\) - \(24.03\% \approx 24\%\) - \(124.97 \approx 125\) - \(8.01 \approx 8\) - \(\sqrt{99.99} \approx \sqrt{100} = 10\) Now we can rewrite the equation using these approximations: \[ \frac{144}{\sqrt[4]{?}} + 24\% \text{ of } 125 = 8^2 - 10 \] ### Step 3: Calculate \(24\%\) of \(125\) To find \(24\%\) of \(125\): \[ 24\% \text{ of } 125 = \frac{24}{100} \times 125 = \frac{24 \times 125}{100} = 30 \] ### Step 4: Calculate \(8^2 - 10\) Next, we calculate \(8^2 - 10\): \[ 8^2 = 64 \quad \text{and} \quad 64 - 10 = 54 \] ### Step 5: Substitute back into the equation Now we substitute back into the equation: \[ \frac{144}{\sqrt[4]{?}} + 30 = 54 \] ### Step 6: Isolate the term with the question mark To isolate \(\frac{144}{\sqrt[4]{?}}\): \[ \frac{144}{\sqrt[4]{?}} = 54 - 30 = 24 \] ### Step 7: Solve for \(\sqrt[4]{?}\) Now we solve for \(\sqrt[4]{?}\): \[ \sqrt[4]{?} = \frac{144}{24} = 6 \] ### Step 8: Find the value of the question mark To find the value of the question mark, we raise both sides to the power of 4: \[ ? = 6^4 \] Calculating \(6^4\): \[ 6^4 = 1296 \] ### Final Answer The approximate value that should come in place of the question mark is: \[ \boxed{1296} \]
