Root Maths Formulas

Square Root :
If x2 = y then we say that square root of y is x and we write √y = x
So, √4 = 2, √9 = 3, √36 = 6

Cube Root:
The cube root of a given number x is the number whose cube is x.
we can say the cube root of x by 3√x

  • √xy = √x * √y
  • √x/y = √x / √y = √x / √y x √y / √y = √xy / y.

Fractions Maths Formulas

What is fraction ?
Fraction is name of part of a whole.

Let the fraction number is 1 / 8.

Numerator: Number of parts that you of the top number(1)

Denominator: It is the number of equal part the whole is divided into the bottom number (8).
