Question

2ײ=32
10ײ-40=0
ײ=4÷25
​

Answer 1

Respuesta:

Explicación paso a paso:

2ײ = 32

ײ = 32/2

ײ = 16

x = $\sqrt{16}$

x = 4

10ײ - 40 = 0

10ײ  = 40

ײ  = 40/10

ײ  = 4

x = $\sqrt{4}$

x = 2

$x^{2}$ = 4 ÷ 25

x = $\sqrt{4 : 25}$

x = 2 ÷ 5

x = 0.4

Answer 2

Respuesta:

$2 {x}^{2} = 32 \\ x = 4 \\ x = - 4\\ \\ 10 {x}^{2} - 40 = 0 \\ 10 {x}^{2} = 40 \\ {x}^{2} = 4 \\ x = 2 \\ x = - 2\\ \\ {x}^{2} = 4 \div 25 \\ x = \frac{2}{5} \\ x = - \frac{2}{5}$
