Find the value of:
(i) 2⁶    (ii) 9³    (iii) 11²    (iv) 5⁴

Solution:

A larger number can be written using an exponential notation in which there is a base and a smaller raised number called its power or exponent.

Exponent represents how many times the base will be multiplied by itself.

For example, 64 can be written as 2⁶, here 2 is the base, and 6 is the exponent. 

2⁶ means that 2 is multiplied 6 times

8² means 8 is multiplied 2 times.

(i) 2⁶ = 2 × 2 × 2 × 2 × 2 × 2 = 64

(ii) 9³ = 9 × 9 × 9 = 729

(iii) 11² = 11 ×11 = 121

(iv) 5⁴ = 5 × 5 × 5 × 5 = 625
