n = +5 or -5
"x squared equals to 25" is not an inequality! You need to re-think the question!
no. 33 is an answer though.
5 to the second power
25 cm to the third power equals 156,250mm
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
4x+9=25 4x=16 x=4
5r = 25 is a linear equation in one variable, r. The solution is r = 5.
