simplify 7x^3y(3xy^5)

Solution

simplify

7 x^{3} y (3 x y^{5})

Solution

21 x^{4} y^{6}

Solution steps

7 x^{3} y (3 x y^{5})

Apply exponent rule:

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

x^{3} x = x^{3 + 1}

= 7 y \cdot 3 x^{3 + 1} y^{5}

Add the numbers:

3 + 1 = 4

= 7 y \cdot 3 x^{4} y^{5}

Apply exponent rule:

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

y y^{5} = y^{1 + 5}

= 7 \cdot 3 x^{4} y^{1 + 5}

Add the numbers:

1 + 5 = 6

= 7 \cdot 3 x^{4} y^{6}

Multiply the numbers:

7 \cdot 3 = 21

= 21 x^{4} y^{6}
