simplify 5/(b^{-2)}

Solution

simplify

\frac{5}{b ^{- 2}}

5 b^{2}

Solution steps

\frac{5}{b ^{- 2}}

Apply exponent rule:

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

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

= \frac{5}{\frac{1}{b ^{2}}}

Apply the fraction rule:

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

= \frac{5 b ^{2}}{1}

Apply the fraction rule:

\frac{a}{1} = a

= 5 b^{2}

4 x^{2} + 29 = - 20 x

(2 + 3 i)^{2} + (2 - 3 i)^{2}

2 x - 3 (x + 5) = 2 x - (x + 3)

\frac{6 ^{\frac{1}{2}}}{6 ^{\frac{1}{3}}}

(\frac{( 30.03 + 0.21 )}{30.42}) - 1
