Square Roots
Basic formulas in Powers and Roots
Some basic formulas used to solve questions on exponents are:

(a^{m})^{n} = (a^{n})^{m} = a^{mn}

a^{m}.a^{n }= a^{m+n}

a^{m }= 1/a^{m}

a^{m}/a^{n} = a^{mn} = 1/a^{nm}

(ab)^{n} = a^{n}b^{n}

(a/b)^{n} = a^{n}/b^{n}

a^{} = 1
Some basic formulae used to solve questions on roots are:

^{n}√a = a^{1/n}

^{n}√ab = ^{n}√a*^{ n}√b

^{n}√(a/b) = ^{n}√a / ^{n}√b

(^{n}√a)^{n} = a
