Let's solve the given problems step by step.

1. Calculate [tex]\(\sqrt{36}\)[/tex]:
- We need to find the number which, when multiplied by itself, equals 36.
- Observing, [tex]\(6 \times 6 = 36\)[/tex].
- Therefore, [tex]\(\sqrt{36} = 6.0\)[/tex].

2. Calculate [tex]\(\sqrt{225}\)[/tex]:
- We need to find the number which, when multiplied by itself, equals 225.
- Observing, [tex]\(15 \times 15 = 225\)[/tex].
- Therefore, [tex]\(\sqrt{225} = 15.0\)[/tex].

3. Calculate [tex]\(\sqrt{289}\)[/tex]:
- We need to find the number which, when multiplied by itself, equals 289.
- Observing, [tex]\(17 \times 17 = 289\)[/tex].
- Therefore, [tex]\(\sqrt{289} = 17.0\)[/tex].

So, the answers are:
1. [tex]\(\sqrt{36} = 6.0\)[/tex]
2. [tex]\(\sqrt{225} = 15.0\)[/tex]
3. [tex]\(\sqrt{289} = 17.0\)[/tex]
