 Surds and Indices  General Questions

Laws of Indices:
a^{m} x a^{n} = a^{m + n}
a^{m} = a^{m  n} a^{n} (a^{m})^{n} = a^{mn}
(ab)^{n} = a^{n}b^{n}
a n = a^{n} b b^{n} a^{0} = 1

Surds:
Let a be rational number and n be a positive integer such that a^{(1/n)} = a
Then, a is called a surd of order n.

Laws of Surds:
a = a^{(1/n)}
ab = a x b
= a b (a)^{n} = a
(a)^{m} = a^{m}
