Math question: What is the closest perfect square to the number 7390?

To find the closest perfect square to 7390, we take the square root of 7390, which is approximately 85.988. The perfect squares closest to this value are 84^2 = 7056 (below 7390) and 85^2 = 7225 (above 7390). Therefore, the closest perfect square to 7390 is 7056.

What is the sum of the digits of the number 7390?

The sum of the digits 7 + 3 + 9 + 0 is 19.

Math question: What is the sum of the product of the digits of the number 7390 subtracted by the quotient of its square root and the cube of its last digit?

To solve this, we first find the product of the digits: 7 * 3 * 9 * 0 = 0. Next, we calculate the square root of 7390, which is approximately 85.915. Finally, we divide this value by the cube of the last digit, which is 0, giving us 85.915 / (0^3) = undefined. Therefore, the sum is 0 - undefined, which is indeterminate.
