(3xy)^2x^4y simplifying an expression
DerKrebs [107]

Answer:

36x^6y^3

Step-by-step explanation:

The problem needs application of law of indices

1. (xy)^m = x^my^m

This means common power for terms can be applied to each term individually.

x^a x^b = x^(a+b)\\

Separate power for the terms having  same base can be added together.

_______________________________________________________

we will be using these law of indices in the problem

(3xy)^2x^4y \\=> 3^2x^2y^2x^4y

applied the first rule of indices as mentioned above

3^2x^2y^2x^4y\\=>9*x^(2+4)4y^(2+1)\\=>9*4x^6y^3\\=>36x^6y^3

applied the second rule of indices as mentioned above

Thus, simplified form of (3xy)^2x^4y  is 36x^6y^3.
