Prime factorization of

90 : 2 \cdot 3^{2} \cdot 5

= 3 2 \cdot 3^{2} \cdot 5

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

2 \cdot 3^{2} \cdot 5 = 3^{2} 2 \cdot 5

= 3 3^{2} 2 \cdot 5

Apply radical rule:

a^{2} = a, a \geq 0

3^{2} = 3

= 3 \cdot 3 2 \cdot 5

Multiply the numbers:

2 \cdot 5 = 10

= 3 \cdot 310

Multiply the numbers:

3 \cdot 3 = 9

= 910

Popular Examples

-x^2+18x-81<= 0

- x^{2} + 18 x - 81 \leq 0

simplify (-71+2i)+(88-12i)simplify

(- 71 + 2 i) + (88 - 12 i)

4/(x+1)> 2/(x+3)

\frac{4}{x + 1} > \frac{2}{x + 3}

9 x^{2} \geq 18 x + 7

25 x^{2} = 144
