Simplify (3x^4)^9 / (3^5x^6)^3  using the laws of exponents, then evaluate.    Thank you!

Expert Answers

An illustration of the letter 'A' in a speech bubbles

exponents of exponents multiply, so:





`((3x^4)^9)/((3^5x^6)^3) = (3^9x^(36))/(3^(15)x^(18))`

`a^b/a^c=a^(b-c)`, so:

`(3^9)/(3^(15)) = 3^(-6)` or `1/3^6`



`(3^9x^(36))/(3^(15)x^(18)) = x^(18)/3^6 = x^(18)/729`
