Question

the approximate age of the earth is 4550 million years in exponential form​

Answer 1

Answer:

$455 \times {10}^{4}$

Answer 2

The approximate age of the earth in exponential form​ = 455 × $10^7$ years

Step-by-step explanation:

Given,

The approximate age of the earth = 4550 million years

To find, the approximate age of the earth in exponential form​ = ?

We know that,

1 million = 10 lakhs

= 10 × 100,000 [ ∵ 1 lakh = 100,000]

= 1,000,000

∴ The approximate age of the earth = 4550 million years

= 4550 × 1,000,000 years

= 4550 × $10^6$ years

= 455 × $10^7$ years

Hence, the approximate age of the earth in exponential form​ = 455 × $10^7$ years
