simplify (-9x^4)(-4x^7)(2x^{-2})

simplify

(- 9 x^{4}) (- 4 x^{7}) (2 x^{- 2})

72 x^{9}

Solution steps

(- 9 x^{4}) (- 4 x^{7}) (2 x^{- 2})

Simplify

(- 9 x^{4}) (- 4 x^{7}) : 36 x^{11}

= 36 x^{11} \cdot 2 x^{- 2}

Multiply the numbers:

36 \cdot 2 = 72

= 72 x^{11} x^{- 2}

Apply exponent rule:

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

x^{11} x^{- 2} = x^{11 - 2}

= 72 x^{11 - 2}

Subtract the numbers:

11 - 2 = 9

= 72 x^{9}

2 (x)

2 (6 + 5)

1^{\frac{1}{4}} \cdot 1^{\frac{1}{4}}

4.22 \cdot 1 0^{- 13} \cdot (- \frac{2 π}{0.033 1 ^{2}})
