Question
Express the following in standard form:
Express 2 years in seconds.
Solution
Given, 2 years = 2 × 365 days ...[∵ 1 year = 365 days approx]
= 2 × 365 × 24 hours ...[∵ 1 day = 24 hours]
= 2 × 365 × 24 × 60 min ...[∵ 1 hour = 60 min]
= 2 × 365 × 24 × 60 × 60 s ...[∵ 1 min = 60 s]
= 63072000 s
Standard form of 63072000 = 63072 × 10 × 10 × 10 ...[∵ am × an × (a)m + n]
= 63072 × 103
= 6.3072 × 103 × 104
= 6.3072 × 107 s
