simplify-3isqrt(-72)

simplify

- 3 i - 72

182

Decimal Notation

25.45584 \dots

Solution steps

- 3 i - 72

- 72 = 22 - 9

= - 3 i 22 - 9

Multiply the numbers:

- 3 \cdot 2 = - 6

= - 6 i 2 - 9

= - 62 - 9 i

- 9 = 3 i

= - 62 \cdot 3 ii

Multiply the numbers:

- 6 \cdot 3 = - 18

= - 182 ii

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - 182 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= - 182 (- 1)

Multiply the numbers:

18 (- 1) = - 18

= - (- 18) 2

Remove parentheses:

- (- 18) 2 = 182

= 182

\frac{1}{2} + \frac{4}{8}

2 x^{2} + 19 x - 21

\frac{n ^{2}}{n - 1} - \frac{n + 5}{n}

+ 5 - 4
