To simplify the expression 5^2 - 4 / 5 + 2, we need to follow the proper order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

Step 1: Start by evaluating the exponent.
5^2 is equal to 5 x 5, which gives us 25. So, the expression becomes 25 - 4 / 5 + 2.

Step 2: Next, evaluate any multiplication or division from left to right.
In this case, there is only one division operation: 4 / 5.
Dividing 4 by 5 gives us 0.8. The expression now becomes 25 - 0.8 + 2.

Step 3: Finally, perform the addition and subtraction from left to right.
Subtracting 0.8 from 25 gives us 24.2.
Adding 2 to 24.2 gives us the final result of 26.2.

Therefore, the simplified expression 5^2 - 4 / 5 + 2 equals 26.2, not 3.

powers first:

25-4/5+2

then multiplication and division, left to right:

25 - 0.8 + 2

then addition and subtraction, left to right:

24.2+2
26.2
