What value should go in the empty boxes to complete the calculation for finding the product of
0.98 × 0.73? both numbers are the same; however, only input the number one time in your answer.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i believe it's a.

i'm not sure on this one, most likely correct.
