Answer:

b

Explanation:

The expression √x+3 means the square root of x+3. We can rewrite this as (x+3)^(1/2), using the exponent rule that says taking the square root is the same as raising to the power of 1/2.

So the options become:

a. 3x^(1/2)

b. (x+3)^(1/2)

c. x^(1/2) + 3

d. (3x)^(1/2)

None of the other options match the given expression. So the correct answer is (b) (x+3)^(1/2).
