Decimal Notation

- 9.89949 \dots

Solution steps

- 14 - 7

- 14 = 14 i

= 14 i - 7

- 7 = 7 i

= 14 i 7 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 14 i^{2} 7

= 147 i^{2}

14 = 72

= 727 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

e^{x} > 4

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

t^{3} - 1

11 x = 14

m - 5 \leq 70
