### QUESTION 1 of 10

We use exponents as a shorthand way of writing calculations such as:

31 x 31 x 31 x 31 x 31

This is a multiplication of the base number 31 by itself five times and so can be written as:

315

5 is the exponent

NB This is not the same as 31 x 5

What is the exponent n when we write the following as 31n: (just write the exponent)

31 x 31 x 31 x 31

What is the exponent n when we write the following as 31n: (just write the exponent)

31 x 31 x 31 x 31 x 31 x 31 x 31

What is the exponent n when we write the following as 31n: (just write the exponent)

31 x 31 x 31

What is the exponent n when we write the following as 3n: (just write the exponent)

3 x 3

What is the exponent n when we write the following as 3n: (just write the exponent)

3 x 3 x 3 x 3 x 3 x 3 x 3 x 3

What is the exponent n when we write the following as 3n: (just write the exponent)

3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3

What is the exponent n when we write the following as 23n: (just write the exponent)

23 x 23 x 23 x 23 x 23

What is the exponent n when we write the following as 23n: (just write the exponent)

23 x 23 x 23 x 23 x 23 x 23 x 23

What is the exponent n when we write the following as 23n: (just write the exponent)

23

What is the exponent n when we write the following as 203n: (just write the exponent)

203 x 203 x 203
