Question

What is the solution to the following expression if x=5

​

Answer 1

The value of given expression is 16

Solution:

Given expression is:

`√(x^2) + √(x) * √(x) + 6`

We have to find the value of expression when x = 5

Substitute x = 5

`√(x^2) + √(x) * √(x) + 6\\\\√(5^2) + (√(5) * √(5)) + 6`

We know that,

`√(a) * √(a) = a`

Therefore, the above equation becomes,

`√(5^2) + 5 + 6\\\\√(25) + 5 + 6\\\\5 + 5 + 6 = 10 + 6 = 16`

Thus the value of given expression is 16
