Express each of the following in standard form:
Express 2 years in seconds.
Answer :
Given that,2 years = 2 × 365 days (∵ 1 year = 365 days)
= 2 × 365 × 24 (∵ 1 day = 24 hours)
= 2 × 365 × 24 × 60 min (∵ 1 hr = 60 min)
= 2 × 365 × 24 × 60 × 60 s (∵ 1 min = 60 s)
= 63072000 s
Standard form = 63072 × 10 × 10 × 10
= 63072 × 103
= 6.3072 × 104 × 103
Using the law of exponent,
= 6.3072 × 107 s
∴ The standard form is 6.3072 × 107 s
