230

Decimal Notation

10.95445 \dots

Solution steps

(- 2 - 10) (- 3)

(- 2 - 10) (- 3) = - (2 - 10) - 3

= - 2 - 10 - 3

- 10 = 10 i

= - 210 i - 3

- 3 = 3 i

= - 210 i 3 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - 210 i^{2} 3

= - 2103 i^{2}

103 = 30

= - 230 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= - 230 (- 1)

Multiply the numbers:

2 (- 1) = - 2

= - (- 2) 30

Remove parentheses:

- (- 2) 30 = 230

= 230

(3 - x)^{2} - 9 = 0

lo g_{2} (5 x)

- 5 + \frac{2}{3} 5 + 4 x - x^{2}

5 + 7 x + 2 = 5 x - 14

z^{2} + z - 2 = 0
