Express Diameter of Earth = 12756000 m in standard form.

Answer»

Diameter of Earth = 12756000 m

A given number is said to be in standard form if it can be expressed as k × 10n, where k is a real number such that 1 ≤ k < 10 and n is a positive integer.

Then,

Diameter of Earth = 12756000 m

= (1.2156 × 107) m (in standard form)
