Calculati, macar un exercițiu.

Answer 1

rad=√

2)
a) -7*-8=56
b) 3/4*(-4/3)=-12/12=-1
c)5/2* 0.4= 2/2=1
d)-3*rad5=-3rad5=-rad45
e)=-4rad5=-rad80
f)=3rad7/2=-rad63/2
g)=1
h)=-rad3*2/rad3=-2

3. 
a) =3/4 * 2= 3/2    b) =-5/6 * 1/10=-5/60     c) =0.5*-4=2

4.
a) =9 rad3   b)=4 rad3   c)=rad5   d)=-10π

Answer 2

Ex 2 a)
-7*(-8)=56
3/4*-4/3=0.75*-1.33=-09975
5/2*0.4=2.5*0.4=1
-3*√5=-3*2.23=6.69
