x la puterea a 2 = 0
x la puterea a 2 = 1
x la puterea a 2 = 49
x la puterea a 2 = 16
x la puterea a 2 = 25
x la puterea a 2 = 16 supra 25
2x la puterea a 2 = 32
2x la puterea a 2 = 50
VA ROG MUULT!

Answer 1

1. x=0
2. x=1
3. x=7
4. x=4
5. x=5
6. x=4 supra 5
7. x=radical din 2
8. x=

Answer 2

$x^{2} =0 \\ x=0$
$x^{2} =1 \\ x= \sqrt{1} , \sqrt{-1}$
$x^{2} =49 \\ x=7$
$x^{2} =16 \\ x=4$
$x^{2} =25 \\ x=5$
$x^{2} = \sqrt{ \frac{16}{25} } \\ x= \frac{4}{5}$
$2 x^{2} =32 \\ x^{2} =32|2 \\ x^{2} =16 \\ x=4$
$2 x^{2} =50 \\ x^{2} =50|2 \\ x^{2} =25 \\ x=5$
