simplify 7x^2y^5(9x^3y)

Solution

simplify

7 x^{2} y^{5} (9 x^{3} y)

Solution

63 x^{5} y^{6}

Solution steps

7 x^{2} y^{5} (9 x^{3} y)

Apply exponent rule:

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

x^{2} x^{3} = x^{2 + 3}

= 7 y^{5} \cdot 9 x^{2 + 3} y

Add the numbers:

2 + 3 = 5

= 7 y^{5} \cdot 9 x^{5} y

Apply exponent rule:

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

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

= 7 \cdot 9 x^{5} y^{5 + 1}

Add the numbers:

5 + 1 = 6

= 7 \cdot 9 x^{5} y^{6}

Multiply the numbers:

7 \cdot 9 = 63

= 63 x^{5} y^{6}
