simplify 15x^{-1}y^7z^2

simplify

15 x^{- 1} y^{7} z^{2}

\frac{15 y ^{7} z ^{2}}{x}

Solution steps

15 x^{- 1} y^{7} z^{2}

Apply exponent rule:

a^{- 1} = \frac{1}{a}

x^{- 1} = \frac{1}{x}

= 15 \cdot \frac{1}{x} y^{7} z^{2}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{15 \cdot 1 \cdot y ^{7} z ^{2}}{x}

Multiply the numbers:

15 \cdot 1 = 15

= \frac{15 y ^{7} z ^{2}}{x}

(a - 6)^{4}

(x - 2 y)^{6}

\frac{5}{15 b - b}

5 x y (x + 1) + 10 x (x + 1)

24 x^{2} \cdot y + 36 x^{3} \cdot y^{2} - 12 x^{4} \cdot y^{3}
