- 72

Decimal Notation

- 9.89949 \dots

Solution steps

- 7 - 14

- 7 = 7 i

= 7 i - 14

- 14 = 14 i

= 7 i 14 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 7 i^{2} 14

= 714 i^{2}

14 = 72

= 772 i^{2}

Apply radical rule:

a a = a, a \geq 0

77 = 7

= 72 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 72 (- 1)

Multiply the numbers:

7 (- 1) = - 7

= - 72

40 (x + 3) - 3 x (x + 3) = 40 x

- 8 x + 14 \geq 60 or - 4 x + 50 < 58

2 (x - 2) + 3 x < 5 x + 6

0.06 = (0.000001) (256) (256 - x)

9 (\frac{x}{3} - 6 x) + 8 = - (- 2 x + 5)
