simplify (sqrt(-21))/(sqrt(7))

simplify

\frac{- 21}{7}

3 i

Solution steps

\frac{- 21}{7}

Apply radical rule:

\frac{a}{b} = \frac{a}{b}

\frac{- 21}{7} = \frac{- 21}{7}

= \frac{- 21}{7}

\frac{- 21}{7} = - 3

= - 3

Apply radical rule:

- a = - 1 a

- 3 = - 1 3

= - 1 3

Apply imaginary number rule:

- 1 = i

= 3 i

(1.2 \cdot 1 0^{7}) (5 \cdot 1 0^{- 6})

12000 (1 + 0.01)^{(- 24)}

(- e^{- x}) (x e^{- x})

a^{c} \cdot b^{c}

x + 3 \cdot x + 4
