simplify sqrt(144)+sqrt(-98)-sqrt(121)+sqrt(-2)

simplify

144 + - 98 - 121 + - 2

1 + 82 i

Solution steps

144 + - 98 - 121 + - 2

144 = 12

- 98 = 2 \cdot 7 i

121 = 11

- 2 = 2 i

= 12 + 2 \cdot 7 i - 11 + 2 i

Group like terms

= 2 \cdot 7 i + 2 i + 12 - 11

Add similar elements:

2 \cdot 7 i + 2 i = 82 i

= 82 i + 12 - 11

Subtract the numbers:

12 - 11 = 1

= 82 i + 1

Rewrite in standard complex form:

1 + 82 i

= 1 + 82 i

(\frac{2}{2})^{2} + (\frac{2}{2})^{2}

(3 x - 1) (x - 3)

64 - 125 x^{3}

\frac{30 x ^{4} y ^{5}}{50 x ^{6} y ^{7}}

\frac{1}{8} \times 2
