simplify-sqrt(1)+sqrt(-81)-sqrt(16)-sqrt(-1)

simplify

- 1 + - 81 - 16 - - 1

- 5 + 8 i

Solution steps

- 1 + - 81 - 16 - - 1

- 1 = - 1

- 81 = 9 i

16 = 4

- 1 = i

= - 1 + 9 i - 4 - i

Group like terms

= 9 i - i - 1 - 4

Add similar elements:

9 i - i = 8 i

= 8 i - 1 - 4

Subtract the numbers:

- 1 - 4 = - 5

= 8 i - 5

Rewrite in standard complex form:

- 5 + 8 i

= - 5 + 8 i

\frac{x ^{2} - 3 x y - 10 y ^{2}}{5 y ^{2} + 4 x y - x ^{2}}

\frac{\frac{( x ^{2} - 1 )}{24}}{\frac{( x + 1 ) ^{2}}{36}}

(3 a - b)^{2}

\frac{150}{25}
