simplify-(sqrt(-14))(sqrt(-21))

simplify

- (- 14) (- 21)

76

Solution steps

- (- 14) (- 21)

- (- 14) (- 21) = - - 14 - 21

= - - 14 - 21

- 14 = 7 - 2

= - 7 - 2 - 21

- 21 = 7 - 3

= - 7 - 2 7 - 3

Apply radical rule:

a a = a, a \geq 0

77 = 7

= - 7 - 2 - 3

- 2 = 2 i

= - 72 i - 3

- 3 = 3 i

= - 72 i 3 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - 72 i^{2} 3

= - 723 i^{2}

23 = 6

= - 76 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= - 76 (- 1)

Multiply the numbers:

7 (- 1) = - 7

= - (- 7) 6

Remove parentheses:

- (- 7) 6 = 76

= 76
