Answer 2

To square each of the given expressions, you simply need to multiply the expression by itself. Here are the squared expressions:

1. $(a + 1/7)^2 = (a + 1/7)(a + 1/7)$

2. $(1/9 + b)^2 = (1/9 + b)(1/9 + b)$

3. $(n/4 + m/3)^2 = (n/4 + m/3)(n/4 + m/3)$

4. $(k/2 - t/5)^2 = (k/2 - t/5)(k/2 - t/5)$

5. $(4⅓ - x)^2 = (4⅓ - x)(4⅓ - x)$

6. $(y + 3¼)^2 = (y + 3¼)(y + 3¼)$

7. $(z - 5⅕)^2 = (z - 5⅕)(z - 5⅕)$

8. $(4½ + t)^2 = (4½ + t)(4½ + t)$
