Question

Salut, am nevoie de ajutor la niste probleme la matematica, ajutati-ma va rog!
1.
a) (-3supra5)la 2
b)(-3supra7)la 3
c) (-4supra3)la 3
d) (-3supra2)la 4

2.
a) 0,75la 2 - (3supra2)la 3
b) 0.8(3)la 2 - (4supra3)la 2
c) (-2supra3)la 3 + 1,(3)la 2
3.
a) [(-√6)la 3 +14√6]: |-2√12|
b) [18√6+(-√6)la 5]: |-3√18|

Answer 1

1.a) (-3/5)^2=9/25
b) (-3/7)^3=-27/343
c) (-4/3)^3=-64/27
d) (-3/2)^4=81/16

2.a) (0,75)^2-(3/2)^3=
       =(75/100)^2-(3/2)^3
       =5625/10000-27/8
b) 0,8(3)^2-(4/3)^2
    =(75/90)^2-16/9
     =5625/8100-16/9
c) (-2/3)^3+12/9
     =-8/27+12/9
