3x squared - x squared = 2x squared
150 and 30
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
Sin squared, cos squared...you removed the x in the equation.
If you mean a2 x a2... the answer is a4
2 squared X 3 squared = 5 squared
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
X squared = x+6 6+x=x squared X=6
a^2b^2c^2 ^2 is squared
x squared (x)X(x) x^2 x2
