simplify sqrt(144)-sqrt(-100)+sqrt(36)-sqrt(-81)

simplify

144 - - 100 + 36 - - 81

18 - 19 i

Solution steps

144 - - 100 + 36 - - 81

144 = 12

- 100 = 10 i

36 = 6

- 81 = 9 i

= 12 - 10 i + 6 - 9 i

Group like terms

= - 10 i - 9 i + 12 + 6

Add similar elements:

- 10 i - 9 i = - 19 i

= - 19 i + 12 + 6

Add the numbers:

12 + 6 = 18

= - 19 i + 18

Rewrite in standard complex form:

18 - 19 i

= 18 - 19 i

\frac{\frac{n ^{2} - 16}{3}}{\frac{n + 4}{21}}

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

2^{x} + 2^{x}

\frac{e ^{- 2} \cdot 2 ^{2}}{2 !}

x^{2} - 8 x + 16
