Răspuns :
4/6 simplificat cu 2 = 2/3
V(9/4) = V9/V4 = 3/2
-V2,25 = -V(225/100) = -V225/V100 = -15/10 = -3/2
2/3+3/2-3/2 = 2/3
Răspuns:
Explicație pas cu pas:
4/6 = (4:2)/(6:2) = 2/3
√(9/4) = √(3/2)² = 3/2
√(2,25) = √(1,5)² = 1,5 = 15/10 = (15:5)/(10:5) = 3/2
____________________
4/6 + √(9/4) + ( -√2,25 ) = 2/3
= 2/3 + 3/2 - 3/2 =
= 2/3
