- 15 \cdot - 25

- 515

Decimal Notation

- 19.36491 \dots

Solution steps

- 15 - 25

- 15 = 5 - 3

= 5 - 3 - 25

- 25 = 5 - 5

= 5 - 3 5 - 5

Apply radical rule:

a a = a, a \geq 0

55 = 5

= 5 - 3 - 5

- 3 = 3 i

= 53 i - 5

- 5 = 5 i

= 53 i 5 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 53 i^{2} 5

= 535 i^{2}

35 = 15

= 515 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 515 (- 1)

Multiply the numbers:

5 (- 1) = - 5

= - 515

- \frac{1}{2} \cdot 1

(- \frac{2}{3})^{4}

\frac{1}{5} x < 2

- 3 (x + 5) - x + 3 = 20

1 + \frac{3}{5}
