Question

This sounds very stupid but what is the square root of 4a?

Answer 1

sqrt4 times sqrta maybe

Answer 2

why do you need to determine sqrt(4a) ?

Answer 3

I simply need to find sqrt of 4a. Some people say it's 2a but 2a^2=4a^2 which ISN'T the same as 4a. But then if we assume it's simply 2, where does a go?

Answer 4

a is some value, which is not determined, so it remains as sqrta

Answer 5

sqrt = ^1/2 \

sqrt(4a)

(4a)^1/2

4^1/2 a^1/2

2 a^1/2
