To simplify the expression, we first need to find the value of the numerator, which is (5 squared - 4).
Since 5 squared is equal to 25, the numerator becomes (25 - 4), which simplifies to 21.
Next, we need to find the value of the denominator, which is 5.
So, the simplified expression is:
start fraction 21 over 5 + 2 end fraction
Now, we add 21 and 2 to get the final answer:
start fraction 23 over 5 end fraction
To simplify the given expression, start by evaluating each part separately.
First, square 5: 5 squared equals 25.
Next, subtract 4 from 25: 25 - 4 equals 21.
Then, find the reciprocal of 5: 1/5.
Next, add 2: 1/5 + 2 equals 21/5.
So, the simplified expression is 21/5 or 4 1/5.
