Step-by-step explanation:

To evaluate (1.03)² using the provided formula for the plus equation:

(a)² + 2ab + (b)²

In this case:

a = 1.03

b = 1

Now, plug these values into the formula:

(1.03)² + 2(1.03)(1) + (1)²

Calculate each term:

(1.0609) + 2(1.03) + 1

Now, perform the multiplications and additions:

1.0609 + 2.06 + 1

Finally, add these values together:

1.0609 + 2.06 + 1 = 4.1209

So, (1.03)² is equal to approximately 4.1209.

Verified answer

The a² + b² Formula is a² + b² = (a +b)² – 2ab and also written as, a² + b² = (a -b)² + 2ab.
