1.	A sugar factory has annual sales of 3 billion 720 million kilograms of sugar. Express this number in the standard form.
Answer» Annual sales of sugar in sugar factory = 3 billion 720 million kilograms = 3720000 kg ∴ standard form of 3720000 kg = 372 × 10 × 10 × 10 × 10 kg = 372 × 10⁴ kg = 3.72 × 10⁴ × 10² kg Using the law of exponent, a^m x aⁿ = a^m+n = 3.72 × 10⁶ kg ∴ The number in the standard form is 3.72 × 10⁶ kg

A sugar factory has annual sales of 3 billion 720 million kilograms of sugar. Express this number in the standard form.

Answer»

Annual sales of sugar in sugar factory = 3 billion 720 million kilograms = 3720000 kg

∴ standard form of 3720000 kg = 372 × 10 × 10 × 10 × 10 kg

= 372 × 10⁴ kg

= 3.72 × 10⁴ × 10² kg

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

= 3.72 × 10⁶ kg

∴ The number in the standard form is 3.72 × 10⁶ kg
