simplify sqrt(-14)*sqrt(-18)

simplify

- 14 \cdot - 18

- 67

Solution steps

- 14 - 18

- 14 = 2 - 7

= 2 - 7 - 18

- 18 = 2 - 9

= 2 - 7 2 - 9

Apply radical rule:

a a = a, a \geq 0

22 = 2

= 2 - 7 - 9

- 7 = 7 i

= 27 i - 9

- 9 = 3 i

= 27 i 3 i

Multiply the numbers:

2 \cdot 3 = 6

= 67 ii

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 67 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 67 (- 1)

Multiply the numbers:

6 (- 1) = - 6

= - 67

\frac{1}{5} - \frac{2}{3}

- x \cdot x^{2}

\frac{1}{1 - cos ( θ )} + \frac{1}{1 + cos ( θ )}

4 x^{4} - 8 x^{3} + 12 x^{2}

32 x^{2}
