What is the solution is the of this equation root 7- 1 divide by root 7 plus 1 - root 7 plus 1 divide by root 7 - 1?
It will depend on where you put your parentheses.
Root 7 -( 1/root 7) is different from (root 7-1)/root 7.

True, but a more helpful answer:
[sqrt(7) - 1]/[sqrt(7) + 1] - [sqrt(7) + 1]/[sqrt(7) - 1]
Multiplying the numerator and denominator of the first fraction by [sqrt(7) - 1]
and the second fraction by [sqrt(7) + 1]
= [sqrt(7) - 1]2/[7 - 1] - [sqrt(7) + 1]2/[7 - 1]
=[7 - 2*sqrt(7) + 1]/6 - [7 + 2*sqrt(7) + 1]/6
= 16/6 = 8/3

What is the root of 2m plus 7 equals 8 plus m?
We're not sure what the question means by "root". It may be what's usuallyreferred to as the "solution" of the equation ... the number that 'm' must be inorder to make the equation a true statement.
