Question

Simplify the expression

Answer 1

9

Explanation:

1 times 1 = 9

Answer 2

1 Simplify

3x^2/10 x 9x^3 x 25

2 Simplify 10\times 9x^3\times 25 to 2250x^3

3x^2/2250^3

3 Take out the constants

3/2250 x x^2/x^3

4 Simplify 3/2250 to 1/750

1/750 x x^2/x^3

5 Simplify

x^2/750x^3

6 Use Quotient Rule: x^a/x^b = x^a-b
x^2-3/750

7 Simplify 2-3 to -1

x^-1/750

8 Use Negative Power Rule: x^-a = 1/x^a

1/x /750

9 Simplify

1/750x is the answer. :)

I hope this help[s. :)
