first of all, have a look at each side separately to see you you can cancel anything down.e.g. the square and square root can cancel out. => sq.root(6²+8²) = 6+8on the otherside, ...

27^-2/31/(27^2/3)1/(27^1/3)²1/3²= 1/9

The length of an arc between two points on a curve can be calculated in two ways; as the integral of ((dy/dx)^2 + 1)^1/2 between the values of the points, or as the integral of ((dy/dt)^2+(dx/dt)^2)^1/2 b...

To find 125^1/3 we have to solve x³ = 125 => This gives x=5 Then we have 2^-3 is equal to 1/(2³) => This is equal to 1/8So to answer the question we have 5*...

factorise x³+2x²+x=0 => x(x²+2x+1)=0 => x(x+1)(x+1)=0 => x(x+1)²=0 => This leads to x=0 and (x+1)²=0 so x=0 and x+1=0 => Giving us the...
