Question

Write the following numbers in exponential form. Also state the
a) base b) exponent and c) how it is read.

i) 32 

ii) 64 

iii) 256 

iv) 243 

v) 49

Answer 1

i) 32 = 2 × 2 × 2 × 2 × 2 = 2⁵

Base = 2; exponent = 5; read as 2 raised to the power 5.

ii) 64 = 2 × 2× 2 × 2 × 2 × 2 = 2⁶

Base = 2; exponent = 6 and we read it as 2 raised to the power 6.

iii) 256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2⁸

Base = 2, exponent = 8 and we read it as 2 raised to the power 8.

iv) 243 = 3 × 3 × 3 × 3 × 3 = 3⁵

Base = 3; exponent = 5 and we read it as 3 raised to the power 5.

v) 49 = 7 × 7 = 7²

= 7 is the base ; exponent = 2.
