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

Solution

simplify

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

Solution

45 x^{16} y^{5}

Solution steps

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

Apply exponent rule:

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

x^{7} x^{9} = x^{7 + 9}

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

Add the numbers:

7 + 9 = 16

= 5 \cdot 9 x^{16} y^{5}

Multiply the numbers:

5 \cdot 9 = 45

= 45 x^{16} y^{5}
