x^8 / x^2 = x^6 You will notice it is just a matter of subtracting exponents.
8 + X SQUARED
7x + 8
That's the same as x to the power minus two.
x2 divided by x would simply be x.
x2/(-x) = -x.
In general:Power = energy transfer divided by timeIn electric circuits:Power = current x voltage x power factorPower = current squared x resitancePower = voltage squared / resistance
Your expression is this... x2 + y2/x
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
8 squared = 8 x 8 = 64
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
X2 (X squared)
1. Anything divided by itself always equals 1.
First, factorising, we get: x2 - 6x - 16 = (x - 8)(x + 2). Then, (x2 - 6x - 16) / (x - 8) = x + 2.
(8 - x)(8 + x)
8 squared is 64(8 x 8 = 64)
x(x + 8)
