Question

Vă rog ajutati ma! Comparati numerele:
A=[(2,5+1,5-1,75):5+0,55] la puterea a 3.
B=(2 1/3+3 1/2):7/12-[2,(3):1/3-3:0,3+1,5:(1/2) la puterea a 2] la puterea a 2

Answer 1

A=[(2,5+1,5-1,75):5+0,55]³=
=(2,25:5+0,55)³=
=(0,45+0,55)³=
=1³=
=1

 B=(2 1/3+3 1/2):7/12-[2,(3):1/3-3:0,3+1,5:(1/2)²]²=
=(7/3+7/2):7/12-[(23-2)/9:1/3-10+1,5:1/4]²=
=(14+21)/6 ×12/7-(21/9 ×3-10+1,5:0,25)²=
=35/6 ×12/7-(7-10+6)²=
=10-(3)²=
=10-9=
=1

A=B
