Question

Fie a=144 , b=25.Aflati valoarea expresiei :
a)a√b
b)b√a
c)√ab
d)√a·√b
e)a+√b
f)√a+b
g)√a+b

Answer 1

a) a rad. b= 144 X rad. 25 = 144X 5 = 720
b) 25 rad. 144 = 25 X 12 = 300
c) rad. a X b = rad. 144 X 25 = rad. 3600 = 60
d) rad. 144 X rad. 25 = 12 X 5 = 60
e) 144 + rad. 25 = 144 + 5 = 149
f) rad. 144 + 25 = 12 + 25 = 37
g) e acelaşi subpunct ca cel precedent.
