a)
2* 3√(x+2) = -4 3√ es raíz cubica
3√(x+2) = -4/2
3√(x+2) = -2
x+2 = (-2)³
x+2=-8
x = -8-2
x = -10
a) (3/4)^9 : (3/5)^5
(3/4)^(9-5)
(3/4)^4
(3^4 )/(4^4)
81/256
b) (x^5*x^-3)/x^4
x^(5-3-4)
x^-2
1/x²
c) [(1/5)^-1)]²
(1/5)^(-1*2)
(1/5)^-2
(5/1)²
5²
25
d) √(16+9) = √25 = 5
e) 3√√64 = 3√8 = 2
f) √(4*25) =
√4*√25 =
2*5 =
10
b) 3/5 x - (1/2 x -2) = x + 3/10
3/5 x -1/2 x +2 = x + 3/10 ; multiplicando todo por 10 se eliminan denominadores
6x - 5x +20 = 10x + 3
6x-5x-10x = 3-20
-9x = -17
x = -17/-9
x = 17/9
