Multiply (2.3 × 10–5)(3.1 × 1012) a. 7.13 × 107 b. 7.13 × 10–60 c. 5.4 × 107 d. 5.4 × 108

7.13*10^7

Step-by-step explanation:

2.3 * 10^-5   * 3.1 * 10^12

We multiply the numbers out front and then add the powers of 10

2.3 * 3.1   * 10^(-5+12)

7.13 * 10^7

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.
