Subpunctul A
E URGENT!!!

Answer 1

Răspuns:

2x×8x=5×125

16x²=625 /÷16 ceva de genu

Answer 2

a)

$2 \times x \times x \times 8 = 125 \times 5$

$\sqrt{2 \times 8 \times x \times x} = \sqrt{5 \times 125}$

|4×x|=25

$= > 4x = 25 \: \: \: sau \: \: \: 4x = - 25$

$x = \frac{25}{4} \: \: \: sau \: \: \: \: x = - \frac{25}{4}$
