simplify sqrt(-6)*sqrt(-3)

simplify

- 6 \cdot - 3

- 32

Decimal Notation

- 4.24264 \dots

Solution steps

- 6 - 3

- 6 = 6 i

= 6 i - 3

- 3 = 3 i

= 6 i 3 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 6 i^{2} 3

= 63 i^{2}

6 = 32

= 323 i^{2}

Apply radical rule:

a a = a, a \geq 0

33 = 3

= 32 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 32 (- 1)

Multiply the numbers:

3 (- 1) = - 3

= - 32

1 \frac{1}{2} \cdot \frac{1}{2}

f (a) = \frac{2 a ^{2} + a - 3}{1 - a ^{3}}

\frac{5}{8} + \frac{4}{6}

f (x) = \frac{( x ^{3} - 21 x - 20 )}{x + 4}

f (x) = \frac{2 x + 6}{x + 3}
