Question

va rog ma ajutati la urmatoarele exercitii??
a) 2 la puterea 74:(2 la puterea a 3 X 2 la puterea 70) +103 x (2+2 x 102)=
b) ( 2 la puterea a 3)puterea 3 : 2 la puterea 8 +6 la puterea 2:(2x3la puterea 2
c) (1+2 la puterea 2)x(3 la puterea 2 : 9-1) : 8+ 1987 la puterea 0
d) 1 la puterea 1997+3 la puterea 0 x 2 la puterea 3 - 1997 la puterea 1998 :1997 la puterea 1998

Answer 1

a)2la 74:(2la 3x2la 70)+103x(2+2x102)=
2la 74:2la 73+103x(2+204)=
2 la 1+103x206=
2+103x2x103=
2+2x103 la 2=
2(1+103 la2)

b)(2la 3)la3:2 la8+6 la2:(2x3 la2)= 
2la9:2la 8+36:(2x9)=
2+36:18=
2+2=4

c)(1+2 la2)x(3la2:9-1):8+1987 la 0=
(1+4)x(9:9-1):8+1=
5x0+1=1

d)1la 1997+3 la0x2la 3-1997la 1998:1997la 1998=
1+1x8-1=8
