Solution

simplify

(- 2)^{\frac{1}{2}}

Solution

2 i

Solution steps

(- 2)^{\frac{1}{2}}

Apply radical rule:

a^{\frac{1}{2}} = a

(- 2)^{\frac{1}{2}} = - 2

= - 2

Apply radical rule:

- a = a - 1

- 2 = 2 - 1

= 2 - 1

Apply imaginary number rule:

- 1 = i

= 2 i

2(2x-1)=(x+1)+3(x-1)

2 (2 x - 1) = (x + 1) + 3 (x - 1)

600x^2-4000x+55000=200000

600 x^{2} - 4000 x + 55000 = 200000

simplify ((2a}{3b})(\frac{4b)/5)+a simplify

(\frac{2 a}{3 b}) (\frac{4 b}{5}) + a

factor 16-x^2 factor

16 - x^{2}
