Express in standard form:Express 5 hectares in cm2 (1 hectare = 10000

1.	Express in standard form:Express 5 hectares in cm2 (1 hectare = 10000 m2)
Answer» Given that, 5 hectares = 5 × 10000 m² (∵1 hectare = 10000 m²) = 5 × 10000 × 100 × 100 cm² Standard form = 5 × 10000 × 100 × 100 = 5 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 Using the law of exponent, a^m x aⁿ = a^m+n = 5 × 10⁸ cm² ∴ The standard form is 5 × 10⁸ cm²

Answer»

Given that, 5 hectares = 5 × 10000 m² (∵1 hectare = 10000 m²)

= 5 × 10000 × 100 × 100 cm²

Standard form = 5 × 10000 × 100 × 100

= 5 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10

Using the law of exponent, a^m x aⁿ = a^m+n

= 5 × 10⁸ cm²

∴ The standard form is 5 × 10⁸ cm²
