simplify sqrt(-2)*sqrt(-6)

simplify

- 2 \cdot - 6

- 23

Decimal Notation

- 3.46410 \dots

Solution steps

- 2 - 6

- 2 = 2 i

= 2 i - 6

- 6 = 6 i

= 2 i 6 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 2 i^{2} 6

= 26 i^{2}

6 = 23

= 223 i^{2}

Apply radical rule:

a a = a, a \geq 0

22 = 2

= 23 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 23 (- 1)

Multiply the numbers:

2 (- 1) = - 2

= - 23

9 w^{2} - 30 w = - 25

9 (x - 7) = - 3 (x + 53)

3 x - 4 > 8

\frac{x}{3} + 2 = \frac{x}{3}

45 \cdot \frac{π}{180}
