Answer

First, calculate the numerator: 29^3 = 24389. Then perform the subtraction: 24389 - 4.6 = 24384.4. Next, calculate the denominator: \sqrt{35} \approx 5.91608 - 1.9 = 4.01608. Now divide the results: 24384.44.01608≈6074.986478\frac{24384.4}{4.01608} \approx 6074.986478. Thus, the figures displayed on the calculator are 6074.986478.

Step 2
