simplify ((2.5)^{-3})/((2.5)^0)

simplify

\frac{( 2.5 ) ^{- 3}}{( 2.5 ) ^{0}}

0.064

Solution steps

\frac{2. 5 ^{- 3}}{2. 5 ^{0}}

Apply exponent rule:

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

= 2. 5^{- 3 - 0}

Subtract the numbers:

- 3 - 0 = - 3

= 2. 5^{- 3}

Apply exponent rule:

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

= \frac{1}{2. 5 ^{3}}

2. 5^{3} = 15.625

= \frac{1}{15.625}

Divide the numbers:

\frac{1}{15.625} = 0.064

= 0.064

15 - (- 3)

\frac{2}{10} + \frac{3}{10}

- 9 x - \frac{5 x}{7}

(- i)^{- 5}

(x^{2} + 9 x + 7) (3 x^{2} + 9 x + 5)
