Recall

Standard form — objective 1

Maths4U Original · Short practice

Let \(\displaystyle N=\)\(6400000\). Here a and n denote the standard-form coefficient and exponent, not given constants.

Write \(\displaystyle N=a\times 10^{n}\) in standard form. Find a.

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.
