Question: If 78 is divided by the sum of its digits and then multiplied by the difference between the tens digit and units digit, what is the resulting value?

To find the resulting value, we first add the digits of 78, which are 7 and 8. Their sum is 7 + 8 = 15. Next, we calculate the difference between the tens digit (7) and the units digit (8), which gives us 7 - 8 = -1. Now, we divide 78 by 15: 78 ÷ 15 = 5.2. Finally, we multiply the quotient, 5.2, by the difference, -1: 5.2 × -1 = -5.2. Thus, the resulting value is -5.2.

Question: If 78 is multiplied by the sum of its digits squared, then divided by the product of its digits, what is the result?

To find the result, let's break down the calculations. The sum of the digits in 78 is 7 + 8 = 15. Squaring 15 gives us 225. The product of the digits in 78 is 7 * 8 = 56. Now, let's calculate: (78 * 225) / 56 = 31250 / 56 = 558.0357. Therefore, the result is approximately 558.0357.

Question: If 78 is multiplied by the sum of its digits plus the cube root of their product divided by the reciprocal of its square, what is the resulting value?

To find the result, we first need to calculate the sum of the digits of 78, which is 7 + 8 = 15. Next, we find the product of these digits: 7 * 8 = 56. The cube root of 56 is approximately 3.7. The reciprocal of 78 squared (1/78^2) is approximately 0.000178. Now, adding 15 and 3.7 and then dividing it by 0.000178 gives us approximately 88,486.19. Therefore, the resulting value is approximately 88,486.19.
