simplify-4sqrt(-63)

simplify

- 4 - 63

- 127 i

Solution steps

- 4 - 63

Prime factorization of

63 : 3^{2} \cdot 7

= - 4 - 3^{2} \cdot 7

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

- 3^{2} \cdot 7 = 3^{2} - 7

= - 4 3^{2} - 7

Apply radical rule:

a^{2} = a, a \geq 0

3^{2} = 3

= - 4 \cdot 3 - 7

Multiply the numbers:

- 4 \cdot 3 = - 12

= - 12 - 7

Apply radical rule:

- a = a - 1

- 7 = 7 - 1

= - 127 - 1

Apply imaginary number rule:

- 1 = i

= - 127 i

- \frac{2}{3} (- \frac{3}{2})

∣ 3 x - 6 ∣ = 15

20 (y) \leq 100

∣ 6 - 2 x ∣ \geq 7

\frac{a ^{2} - 9}{a ^{2} + a - 12}
