Express each of t

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
