VA ROG REPEDE E URGENT
calculati x,xla puterea 2 si xla puterea 3 in fiecare caz
a)x=17,3-8,9
b)x=4 ori 3,6-3 ori 2,8
c)x=2,31+0,01
d)x=5,673-2,663
e)x=5-3,98
f)x=0,2 ori 1,7+1,66-0,9
g)x=1,216+0,184
h)x=4,12 ori 1,2 +0,81

Răspuns :

a) x=8,4 ; x la 2 =70,56; x la 3 - 592,704
b) x- 60,32; x la 2 =15702,5024, x la 3 =947174,945
c- 2,32; xla 2 =5,3824; x la 3 = 12,487168
d- x= 3,01; xla 2= 9,0601; xla3=27,270901
e- x=1,02; xla2=1,0404, xla3=1,061208
f x=1,1; x la2 =1,21; xla3=1,331
g=x=1,4, xla2=1,96, xla3=2,744
h x=5,754, xla2=33,108516, xla3=190,506401
