How do you find the square root of
√a2??? or √a4, for √a4 it thought maybe it was 2√a. am i wrong??

If you mean √(a x 2), usually written as √(2a), then it's already in its simplest form.
You could write it as √2√a if you wanted though.
√(4a) = 2√a, because √4 = 2.
Why did the vector cross the road?
It wanted to be normal.

Also note that the one-half power is the same as a square root.
And the caret ^ sign is used at times to represent the power right after the caret.
Like 81^0.5 is 9 because 9 times 9 is 81, so the square root of 81 is 9.
Also 36^0.5 is 6 because 6 times 6 is 36, so the square root of 36 is 6.
Now if we multiply both of these together, the 6 and the 9, we get 54.
But let's do it with the square roots...
81^0.5 times 36^0.5 should also be 54. But is it??
81
x 36

24 06
4 8
+ 0 3

2916
So 2916 ^ 0.5, is that 54???
54 times 54...
5 4
5 4

25 16
