Answer 1

Răspuns:

a= [ ( 10/4+5/4-3/4) ÷5+2/5] la puterea 5=

a= ( 12 / 4 ÷5/1 +2/5) la puterea 5

a= ( 12/4× 1/5 +2/5) la puterea 5

a= (3/5 +2/5) la puterea 5

a=( 5/5 ) la puterea 5

a= 1 la puterea 5

a=1

b= ( 7/3+7/2) ÷7/12-[ 10/3÷1/3-3÷3/10+3/2÷ (1/2) la puterea2]

b= ( 14/6+ 21/6) ÷ 7/12 -[ 10/3× 3/1 -3 ×10/3 +3/2 ÷ 1/4]

b= 35/6 × 12/7 -( 10 -10 + 3/2×4/1)

b= 5/1 × 2/1 - ( 10-10 + 6)

b= 10 - 6

b=4

b> a
