Math help question..............

use the power rules for exponents to simplify the expression
(5xy)²

convert the number to scientific notation
1,944,000,000

convert the number to scientific notation
0.00000000003

(5xy)^2 =25x^2y^2

1,944,000,000 = 1.944 x 10^9

0.00000000003 = 3 x 10 ^ -11

1) 5^2 * x^2 * y^2
25x^2y^2

2) 1.944 x 10^(9)

3) 3 x 10^(-11)

I hope this information was very helpful.

25x²y²

1.944 x 10^(9)

3 x 10^(-11)
