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

simplify

- 6 \cdot - 2

- 23

Decimal Notation

- 3.46410 \dots

Solution steps

- 6 - 2

- 6 = 6 i

= 6 i - 2

- 2 = 2 i

= 6 i 2 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 6 i^{2} 2

= 62 i^{2}

6 = 23

= 232 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

15 \geq 23 + ∣ y + 5 ∣

2 x^{2} - 3 x < 0

x + 7 > x - 9

\frac{r}{4} < 2

\frac{1}{x} \leq \frac{2}{x + 1} - \frac{1}{x + 2}
