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. :)
