SOLUTION: How do I solve for A and also B with the following equation? (5x^4)(4x^2)=Ax^b My quess A= (5x^4)(4x^2)/x^b so.. A=20x^6/x^b so.. A=20x^(6+b) (Is this answer correct?)

Question 97152: How do I solve for A and also B with the following equation?
(5x^4)(4x^2)=Ax^b
My quess
A= (5x^4)(4x^2)/x^b so..
A=20x^6/x^b so..
A=20x^(6+b) (Is this answer correct?)
B= I don't know how to solve this.

Given
=
applying the law of indices =
=
Equate the coefficients on both sides
20= A
Equating the powers on both sides
6=B
A=20
B=6
