Answer 1

================================

Answer 2

f )

( 1 + 1,8² · 100 ) : ( 2,4 · 15 - 0,1³ · 1000 · 11 ) = 13

= ( 1 + 3,24 · 100 ) : ( 36 - 0,001 · 1000 ·11 ) =

= ( 1 + 324 ) : ( 36 - 11 ) =

= 325 : 25 =

= 13

g)

5,2 + 5, (2 ) - 5,02 - 5,0( 2 ) =

= 52 / 10 + ( 52 - 5 ) / 9 - 502 / 100 -  ( 502 - 50 ) / 90 =

= 26 / 5 + 47 / 9 - 251 / 50 - 226 / 45 = 0,38

= c.m.m.m.c al numitorilor ( 5; 9;  50;  45 ) = 2 x 3² x 5² = 450

= ( 26 × 90  + 47 × 50  - 251 × 9 - 226 × 10 ) / 450 =

= ( 2 340 + 2 350 - 2 259 - 2 260 ) /  450 =

= ( 2 431 - 2 260 0 / 450 =

= 171 / 450 =

= 57 / 150 =

= 19 / 50 =

= 0,38
