Question

Evaluate √x + 21 when x = 4.
Write the answer in simplified radical form.

Answer 1

To evaluate the expression sqrt(x) + 21 when x = 4 and write the answer in simplified radical form.

Step-by-step explanation:

To evaluate the expression √x + 21 with x = 4, we substitute the value of x into the expression.

√4 + 21 = 2 + 21 = 23

So, the answer is 23.

However, the question asks for the answer in simplified radical form. Since 23 is not a perfect square, it cannot be simplified further as a radical.
