To simplify the expression, we start by solving each part separately:
5 squared is 5 x 5 = 25.
4 divided by 5 is 4/5.
So the expression becomes:
25 - 4/5 + 2.
To add or subtract fractions, we need to have a common denominator. The lowest common denominator for 5 and 1 is 5, so we rewrite the expression as:
25/1 - 4/5 + 10/5.
Now that the fractions have the same denominator, we can combine them:
25/1 - 4/5 + 10/5 = (25 - 4 + 10)/5 = 31/5.
Therefore, the simplified expression is 31/5.
To simplify the expression start with the given expression:
(5^2 - 4) / 5 + 2
First, simplify the exponent:
25 - 4 = 21
Next, divide by 5:
21 / 5 = 4.2
Finally, add 2:
4.2 + 2 = 6.2
So, the simplified expression is 6.2.
