Answer :

To simplify the given expression [tex]\(\left(1+\frac{1}{3}\right)^2-\frac{2}{9}\)[/tex], we'll proceed step-by-step:

1. First, perform the addition inside the parentheses:
[tex]\[ 1 + \frac{1}{3} \][/tex]
Converting 1 to a fraction with a common denominator:
[tex]\[ 1 = \frac{3}{3} \][/tex]
Now add:
[tex]\[ \frac{3}{3} + \frac{1}{3} = \frac{4}{3} \][/tex]

2. Next, square the result of this addition:
[tex]\[ \left(\frac{4}{3}\right)^2 \][/tex]
Calculate the square of [tex]\(\frac{4}{3}\)[/tex]:
[tex]\[ \left(\frac{4}{3}\right)^2 = \frac{16}{9} \][/tex]

3. Then, subtract [tex]\( \frac{2}{9} \)[/tex] from the squared result:
[tex]\[ \frac{16}{9} - \frac{2}{9} \][/tex]
Since the denominators are the same, subtract the numerators:
[tex]\[ \frac{16}{9} - \frac{2}{9} = \frac{14}{9} \][/tex]

Therefore, the simplified form of the expression [tex]\(\left(1+\frac{1}{3}\right)^2-\frac{2}{9}\)[/tex] is:
[tex]\[ \boxed{\frac{14}{9}} \][/tex]
