Simplify 12x to the power of 7 y to the power of 3 divided by 6x to the power of 3 y
Galina-37 [17]

Answer:

2x⁴y²

Step-by-step explanation:

The question gives us the expression;

12x⁷y³ ÷ 6x³y

We are supposed to simplify the expression;

First we could divide the digits;

12 ÷ 6 = 2

Then we divide the like terms;

x⁷ ÷ x³

This means;

=\frac{x*x*x*x*x*x*x }{x*x*x}

= x*x*x*x

=x^4

y³ ÷ y

That is;

=\frac{y*y*y}{y}

=y*y

=y^2

Therefore, the simplified expression will be 2x⁴y²
