Let's first see what exponents are

In 2 5 ,

2 is the base

5 is the exponent (or index)

 

Let's study the law of indices 

Laws of Exponents - Part 11

  • √a = a 1/2

  • āˆ›a = a 1/3

  • n √a = a 1/n

  • a p.  a q = a p + q
  • a p / a q  = a p - q
  • a p.  b p = (ab) p
  • (a p ) q.  = a pq
  • a 0 .  = 1
  • a –n.  = 1/a n
