Question

Express 129000 in the exponential form

Answer 1

129×10^3 is the correct answer

Answer 2

Solution :-

1) Exponential form of 129000 as a product of prime numbers -

129000 = 2 × 2 × 2 × 3 × 5 × 5 × 5 × 43

= 2³ × 3¹ × 5³ × 43¹ 

Hence, exponential form of 129000 as a product of prime numbers is 2³ × 3¹ × 5³ × 43¹

2) Exponential form of 129000 as scientific notation -

129000 = 1.29 × 10⁵

Hence, exponential form of 129000 as scientific notation is 1.29 ×10⁵
