simplify-sqrt(4)+sqrt(-80)-sqrt(1)+sqrt(-20)

simplify

- 4 + - 80 - 1 + - 20

- 3 + 65 i

Solution steps

- 4 + - 80 - 1 + - 20

- 4 = - 2

- 80 = 45 i

1 = 1

- 20 = 25 i

= - 2 + 45 i - 1 + 25 i

Group like terms

= 45 i + 25 i - 2 - 1

Add similar elements:

45 i + 25 i = 65 i

= 65 i - 2 - 1

Subtract the numbers:

- 2 - 1 = - 3

= 65 i - 3

Rewrite in standard complex form:

- 3 + 65 i

= - 3 + 65 i

\frac{9}{5} \div 3

\frac{x ^{3} + 8 x ^{2} + 17 x + 10}{x ^{2} + 2 x}

22 \times 8

\frac{1}{3} x^{\frac{- 2}{3}}

\frac{1}{2} x^{- 1}
