SOLUTION: Could someone please tell me if I am doing this right? Thank you soooo much! Simplify:(2x^5)^3(-3x^4)^3 This is what I got but I feel unsure of my answer. 2x^5*3 = 2x

Question 495583: Could someone please tell me if I am doing this right? Thank you soooo much!
Simplify:(2x^5)^3(-3x^4)^3
This is what I got but I feel unsure of my answer.

2x^5*3 = 2x^15
-3x^4*3 = -3x^12
3*2x^15= 6x^15
-3x^12 * 3 = -9x^12
6x^15 * -9x^12 = -54x^27
= -54x^27
