power and root

Free fall movement is a hight with the original velocity is hero.
example:
v2 = 2gh
with : v : velocity
g : gravitation
h : height from the ground

Relation of exponent and root:
1) Exponents
with example is a^n
it's mean a x a x a x a x......x a, as many as n factor
a : base and n: exponent

Some teorem for expent:

• a^m+a^n = a^m+n
• a^m : a^n = a^m-n
• (a^n)^m = (a)^n.m
• (axb)^m = a^m.b^m
• (a/b)^m = a^m/b^m
