simplify (20xy^7)/(30xy^8)

simplify

\frac{20 x y ^{7}}{30 x y ^{8}}

\frac{2}{3 y}

Solution steps

\frac{20 x y ^{7}}{30 x y ^{8}}

Cancel the common factor:

x

= \frac{20 y ^{7}}{30 y ^{8}}

Factor the number:

20 = 10 \cdot 2

= \frac{10 \cdot 2 y ^{7}}{30 y ^{8}}

Factor the number:

30 = 10 \cdot 3

= \frac{10 \cdot 2 y ^{7}}{10 \cdot 3 y ^{8}}

Cancel the common factor:

10

= \frac{2 y ^{7}}{3 y ^{8}}

Simplify

\frac{y ^{7}}{y ^{8}} : \frac{1}{y}

= \frac{2}{3 y}

1100 t = \frac{0.9}{1 + 20 e ^{- 2.25}}

\frac{1 + i}{2 - i} + \frac{- 3 - 2 i}{1 + 3 i}

∣ 2 x - 2 ∣ = ∣ - 6 ∣

3 - 3 i

x^{3} - 27 x + 54
