simplify (4x^2)(9y)(2xy)

Solution

simplify

(4 x^{2}) (9 y) (2 x y)

Solution

72 x^{3} y^{2}

Solution steps

(4 x^{2}) (9 y) (2 x y)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x = x^{2 + 1}

= 4 \cdot 9 y \cdot 2 x^{2 + 1} y

Add the numbers:

2 + 1 = 3

= 4 \cdot 9 y \cdot 2 x^{3} y

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

yy = y^{1 + 1}

= 4 \cdot 9 \cdot 2 x^{3} y^{1 + 1}

Add the numbers:

1 + 1 = 2

= 4 \cdot 9 \cdot 2 x^{3} y^{2}

Multiply the numbers:

4 \cdot 9 \cdot 2 = 72

= 72 x^{3} y^{2}
