simplify-7x^2(9x^2y^4)

simplify

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

- 63 x^{4} y^{4}

Solution steps

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

Apply exponent rule:

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

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

= - 7 \cdot 9 x^{2 + 2} y^{4}

Add the numbers:

2 + 2 = 4

= - 7 \cdot 9 x^{4} y^{4}

Multiply the numbers:

7 \cdot 9 = 63

= - 63 x^{4} y^{4}

(1 - x)^{- 1}

(x + 1)^{2} (x - 2)^{2}

((((4 x^{3} y^{-} 2)^{3})^{0})^{5})^{-} 4

e^{- 2 x} \cdot e^{- 2 x}
