what is the answer to this math equation (6x10^4)^2

Question

 I need help because I don't know how to solve this 

Answer 1

Assuming you have a scientific notation (6 x 10⁴) and you want it raised to the second power,

(6 x 10⁴)(6 x 10⁴)

(6)(6)(10⁴)(10⁴)

36 x 10⁸

3.6 x 10⁹

Answer 2

use PEMDAS

do what is in the parentheses first (raise to a power first, then multiply), then raise to a power

(6x10^4)^2

(6x10,000)^2

(60,000)^2

60,000x60,000=3,600,000,000
