2.52x = 8
Taking (natural) logs: 2x*ln(2.5) = ln(8)
so 2x = ln(8)/ln(2.5) = 2.0794/0.9163 = 2.2694 approx.
and therefore, x = 2.2694/2 = 1.1347 approx.

"x squared equals to 25" is not an inequality! You need to re-think the question!
no. 33 is an answer though.

Well you can find what it equals in terms of x. If you know that y plus y equals 25 to the power of 25 then you know that 2y=25^25 which means that y=(25^25)/2 - this is a huge number. To find x+y you just add x to what y equals so you get x+(25^25)/2
5r = 25 is a linear equation in one variable, r. The solution is r = 5.
