multiply 3/√63 by √63/√63 (this is equal to 1 so it wont change the value. you get (3√63)/63. Simplifying it equals √63/21. You can divide √63 into √9*7. Now you can pull out the √9 to get 3√7. The simplified equation at this point is (3√7)/21. Simplifying the 3 and 21 gets you the (√7)/7)

3/√63 ,factor out 63 the factor is 9&7

= 3√(9X7),get the square root of 9

=3/3√7,cancel out 3

=1/√7,then rationalize the denominator by multiplying √7/√7

=√7/√49,get the square root of 49 is 7

=√7/7,answer

3/√63 =

3/(√9√7) =

3/(3√7) =

1/√7 =

(√7/√7)(1/√7) =

√7/(√7√7) =

√7/7

Because the square root of 63 is ~7.937 and 3/7.937 is ~0.377. The square root of 7 is ~2.645 and if you divide that by 7 it equals the same. Use a calculator.

dis is easy ...

63 can b written as 3*21

=3*7*3

so by taking square we get 3 squareroot(7)

the final answer will be 1/squareroot(7)

by multiplying numerator and denominator with ... squareroot(7) ... we get the result
