Suppose we have a number

  128

 

To write it as exponent,

we do it’s prime factorization

 

128 = 2 × 2 × 2 × 2 × 2 × 2 × 2

128 = 2 7

Similarly,

  For 243

243 = 3 × 3 × 3 × 3 × 3

243 = 3 5

 

Writing numbers as exponents - Part 2

For 625

625 = 5 × 5 × 5 × 5

625 = 5 4

Writing numbers as exponents - Part 3

 

For 18

18 = 2 × 3 × 3

18 = 2 × 3 2

 

  For 72

72 = 2 × 2 × 2 × 3 × 3

72 = 2 3 × 3 2

Writing numbers as exponents - Part 4

 

For 100

100 = 2 × 2 × 5 × 5

100 = 2 2 × 5 2

 

We can also write 100 as

  100 = 10 × 10 = 10 2
