# HOW TO WRITE EXPRESSIONS USING EXPONENTS

The exponent of a number tells us how many times the number is multiplied by itself.

Example : We can write expressions in simplest form using exponents.

Example 1 :

Rewrite (m  m  m  m) in simplest form using an exponent.

Solution :

m is multiplied by itself for four times.

m  m  m  =  m4

Example 2 :

Rewrite (5 ⋅ 5 ⋅ 5) in simplest form using an exponent.

Solution :

5 is multiplied by itself for three times.

⋅ 5 ⋅ 5  =  53

Example 3 :

Rewrite ( 7  5  5 ⋅ 5) in simplest form using exponents.

Solution :

7 is multiplied by itself for two times and 5 is multiplied by itself for three times.

7  5  5 ⋅ 5  =  7⋅ 53

Example 4 :

Rewrite (13  b  b  b ⋅ b) in simplest form using exponents.

Solution :

13 comes once and b is multiplied by itself for four times.

13  b  b  b ⋅ b  =  13b4

Example 5 :

Rewrite (17  17  w  w ⋅ w) in simplest form using exponents.

Solution :

17 is multiplied by itself for two times and w is multiplied by itself for three times.

17  17  w  w ⋅ w  =  172w3

Example 6 :

Rewrite (5  5  p ⋅ p ⋅ p ⋅ p ⋅ p) in simplest form using exponents.

Solution :

5 is multiplied by itself for two times and p is multiplied by itself for five times.

5  5  p ⋅ p ⋅ p ⋅ p ⋅ p  =  52p5

Example 7 :

Rewrite (n  n  n ⋅ b ⋅ b) in simplest form using exponents.

Solution :

n is multiplied by itself for three times and b is multiplied by itself for two times.

n  n  n ⋅ b ⋅ b  =  n3b2

Example 8 :

Rewrite (9  9  9 ⋅ c) in simplest form using an exponent.

Solution :

9 is multiplied by itself for three times and c comes once.

9  9  9 ⋅ c  =  93c

Example 9 :

Rewrite (4  4  4 ⋅ k ⋅ k) in simplest form using exponents.

Solution :

4 is multiplied by itself for three times and k is multiplied by itself for two times .

4  4  4 ⋅ k ⋅ k  =  43k2

Example 10 :

Rewrite (2  2  r ⋅ r ⋅ r) in simplest form using exponents.

Solution :

2 is multiplied by itself for two times and r is multiplied by itself for three times .

2  2  r ⋅ r ⋅ r  =  22r3 Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.
