How much times greater is 9*10^5 than 8*10^2

1125 times greater

Step-by-step explanation:

9*10^5 =9*100000 = 900000

8*10^2 = 8*100 = 800

900000/800 = 9000/8 = 1125

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.

c is the correct answer
