Pressure is defined as the following Pressure = force / area. So what this means is pressure is how much force is exerted over a area of given size. For examle a concrete slab is on the floor this slab has a width of 2m and a length of 2 m its area is 2 x 2 which gives 2m Squared. Its force it exerts is 1000 newtons ok what the hell does this mean? if you place this in the formula you will get pressure = 1000/4 Pressure = 250 newtons per square metre. I hope this answers you question on what pressure is.
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
If 2x2 = 250 then x2 = 250/2 = 125 So x = sqrt(125) = 5*sqrt(5) = +/- 5*2.236 = + or - 11.180
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
x2 + x2 = 2x2 2x^2
x^3 - 121x
x2+y2

X2 A number to the second power is squared.
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
2x2 + x2 = 3x2
x2
To find 250 squared, you calculate (250 \times 250), which equals 62,500. If by "squared 3" you mean to raise 250 squared to the power of 3, you would then compute (62,500^3), which equals 244,140,625,000,000.
