Don't learn square or cube of some number means the two times or three times of that number respectively

like 2² = 2 × 2 = 4 2³ = 2 × 2 × 2 = 8

3² = 3 × 3 = 9 3³ = 3 × 3 × 3 = 27

to do square root bigger values just prime factorize it

like for number 17424

after prime factorization we get 17454 = 11 × 11 × 2 × 2 × 2 × 2 × 3 × 3

so square root =√(11 × 11 × 2 × 2 × 2 × 2 × 3 × 3)

very very two same numbers under root you will get 1 number outside root

that is = √(11 × 11 × 2 × 2 × 2 × 2 × 3 × 3)

= 11× 2 × 2 × 3

=132

some time a case like this can happen like for square root of this number

98

so √98

=√( 2 × 7 × 7 )

= 7√2

now you require value of √2 which you can get by root division

√2 = 1.414

so 7√2 = 7 × 1.414 = 9.898

like 2² = 2 × 2 = 4 2³ = 2 × 2 × 2 = 8

3² = 3 × 3 = 9 3³ = 3 × 3 × 3 = 27

Just split the numbers under root and solve it and just leave an irrational number as it is
