Multiply √(7)*√(3)
I got 2√14 is that right?
Should I put the decimal form instead?

No, it's the square root of 21. You can't simplify that. You just multiply the numbers in the square root signs. Since you can't take a square number out of 21, you cannot simplify it anymore than the square root of 21.

√(7)*√(3) = √(7*3) = √(21)
It cannot be simplified so this as above.
Only convert to decimal form if stated in question.

7 x 3 = 21 and 21 cannot be factored any further
