Question

If ,7 root x-24=11, what is the value of x?

Answer 1

25

Step-by-step explanation:

It's a equation, See in the bottom for method of solution.

Given:

$7 \sqrt{x} - 24 = 11$

To Find:

The value of x

Solution:

$7 \sqrt{x} - 24 = 11 \\ \\ 7 \sqrt{x} = 11 + 24 \\ \\ 7 \sqrt{x} = 35 \\ \\ \cancel{7} \sqrt{x} = \cancel{35} \\ \\ \sqrt{x} = 5$

[Squaring Both Side]

${( \sqrt{x}) }^{2} = {(5)}^{2} \\ \\ \boxed{x = 5}$

Therefore, required value of x is 25.

Point to be Noted

Equation solving is So easy you just need to follow the instructions.

i) First arrange the no. in one side and variable in one side.

ii) The sign will change if we change the no. or variable between equal =. Like + change into - and × change into ÷ .

iii) Use the BODMAS and just go ahead.
