The First Question:

√8

Prime factorization of 8: 2³

= √2³

Apply radical rule: a^b+c = a^b * a^c

2³ = 2² * 2

=√2² * 2

Apply radical rule: √ab = √a√b, a ≥ 0, b ≥ 0

√2² * 2 = √2² √2

Apply radical rule: √a² = a, a ≥ 0

√2² = 2

2√2

The Third question:

√-8

Let's apply radical rule:

√-a = √-1 √
