Square Root and Cube Root - ( Arithmetic Aptitude)

  1. Square Root: Ifx2=y, we say that the square root ofyisxand we writey=x. Thus,4= 2,9= 3,196= 14.
  2. Cube Root: The cube root of a given numberxis the number whose cube isx. We, denote the cube root ofxbyx. Thus,8=2 x 2 x 2= 2,343=7 x 7 x 7= 7 etc. Note: 1.xy=xxy
    2.
