The perfect squares are
- 25
- 100
Step-by-step explanation:
1.
[tex] \sqrt{25} \\ \sqrt{ {5}^{2} } \\ = 5[/tex]
2.
[tex] \sqrt{2} = 1.41421 \\ [/tex]
3.
[tex] \sqrt{99} \\ = \sqrt{9 \times 11} \\ = \sqrt{ {3}^{2} \times 11 } \\ 3 \sqrt{11} [/tex]
4.
[tex] \sqrt{100} \\ = \sqrt{10 \times 10} \\ = \sqrt{ {10}^{2} } \\ = 10[/tex]
