Question

$\frac{4}{6} + \sqrt{ \frac{9}{4} } + ( - \sqrt{2. 25} ) =$
va rog ajutațima dau coroana ​

Answer 1

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

Answer 2

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
