simplify sqrt(-10)*sqrt(-15)

simplify

- 10 \cdot - 15

- 56

Decimal Notation

- 12.24744 \dots

Solution steps

- 10 - 15

- 10 = 5 - 2

= 5 - 2 - 15

- 15 = 5 - 3

= 5 - 2 5 - 3

Apply radical rule:

a a = a, a \geq 0

55 = 5

= 5 - 2 - 3

- 2 = 2 i

= 52 i - 3

- 3 = 3 i

= 52 i 3 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 52 i^{2} 3

= 523 i^{2}

23 = 6

= 56 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 56 (- 1)

Multiply the numbers:

5 (- 1) = - 5

= - 56

\frac{a}{2 a + 2 b} + \frac{b}{2 a + 2 b}

- cos (2 x) + 2 cos^{2} (x)

e^{- 2 + 2}

\frac{5}{5 x}

\frac{28 4}{7}
