simplify sqrt(-2)\times sqrt(-10)

simplify

- 2 \cdot - 10

- 25

Decimal Notation

- 4.47213 \dots

Solution steps

- 2 - 10

- 2 = 2 i

= 2 i - 10

- 10 = 10 i

= 2 i 10 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 2 i^{2} 10

= 210 i^{2}

10 = 25

= 225 i^{2}

Apply radical rule:

a a = a, a \geq 0

22 = 2

= 25 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 25 (- 1)

Multiply the numbers:

2 (- 1) = - 2

= - 25

9 a^{2} - x^{2} + 2 x - 1

\frac{1}{3} \cdot (- \frac{2}{3})

\frac{100}{14}

\frac{2}{5} + \frac{2}{4}

lo g_{5} (5 \times 5)
