# Express each of the following in standard form:Express 2 years in seconds.

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
