The correct Answer is:
To solve the problem `(5.01)^(3) * (23.99)^(2) / (44.98)^(3) = (?)^(2)`, we will approximate the numbers and simplify step by step. ### Step 1: Approximate the numbers We will round the numbers to make calculations easier: - \(5.01 \approx 5\) - \(23.99 \approx 24\) - \(44.98 \approx 45\) Thus, we can rewrite the equation as: \[ (5)^{3} * (24)^{2} / (45)^{3} = (?)^{2} \] ### Step 2: Calculate the powers Now, we will calculate the powers: - \(5^{3} = 125\) - \(24^{2} = 576\) - \(45^{3} = 45 * 45 * 45\) Calculating \(45^{3}\): \[ 45 * 45 = 2025 \] \[ 2025 * 45 = 91125 \] So, we have: \[ (5)^{3} * (24)^{2} = 125 * 576 \] ### Step 3: Calculate \(125 * 576\) Now we will calculate \(125 * 576\): \[ 125 * 576 = 72000 \] ### Step 4: Substitute back into the equation Now we substitute back into the equation: \[ \frac{72000}{91125} = (?)^{2} \] ### Step 5: Simplify the fraction Next, we simplify the fraction: \[ \frac{72000}{91125} \] To simplify, we can find the GCD or use a calculator to get the approximate value. After simplification, we find: \[ \frac{72000}{91125} \approx 0.79 \] ### Step 6: Find the square root Now we take the square root of both sides: \[ ? = \sqrt{0.79} \approx 0.89 \] ### Step 7: Compare with options Now we compare this value with the options given: - \( \frac{8}{9} \approx 0.89 \) - Other options are smaller or larger. Thus, the approximate value of \( ? \) is: \[ ? \approx \frac{8}{9} \] ### Final Answer The approximate value that comes in place of (?) is: \[ \frac{8}{9} \]
