simplify 5y^{-2}

Solution

simplify

5 y^{- 2}

\frac{5}{y ^{2}}

Solution steps

5 y^{- 2}

Apply exponent rule:

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

y^{- 2} = \frac{1}{y ^{2}}

= 5 \cdot \frac{1}{y ^{2}}

Apply the fraction rule:

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

= \frac{5 \cdot 1}{y ^{2}}

Multiply the numbers:

5 \cdot 1 = 5

= \frac{5}{y ^{2}}

ln (x + 1)

5 - (- 2 a + 3) + 4 (1 - a)

x^{4} - x^{2} + 2 x - 1

\frac{4}{1} - \frac{3}{2}

22 \cdot 6
