Question

If 4:x=x:4, then find x​

Answer 1

Answer:

x = 4

Step-by-step explanation:

According to the information provided  in the question it is given as

4:x=x:4,

We need to find the value of x

4:x

x: 4

Let make an equation to get the value of x

By simple cross multiplication  we get

[tex]x\times x = 4\times 4\\ x^{2} =16\\ x=\sqrt{16} [/tex]

Hence

$x = 4$

So the value of x is  4

Answer 2

Given,

4 : x = x : 4

find value of x .

Solution :-

$\rm⇢ \: \: x \times x = 4 \times 4$

$\rm⇢ \: \: {x}^{2} = 16$

$\rm⇢ \: \: x = \sqrt{16}$

$\rm⇢ \: \: x = \pm 4$
