Answer:

Square root and Cube roots are the most important topics in Maths, especially for class 8 students. To find the square root of any number, we need to find a number which when multiplied twice by itself gives the original number. Similarly, to find the cube root of any number we need to find a number which when multiplied three times by itself gives the original number.

Symbol: The square root is denoted by the symbol ‘√’, whereas the cube root is denoted by ‘∛’.

√4 = √(2 × 2) = 2

∛27 = ∛(3 × 3 × 3) = 3
