Question 82 (a)

Express the following numbers in standard form.
76,47,000

Answer 1

We have 76,47,000 = 7647000
A number in standard form is written as $a\times {10}^k$ where a si the terminating decimal such that $1\le a\le 10$ and k is any integer.
So, $7647000=7647\times {10}^3=7.647\times {10}^3\times {10}^3=7.647\times {10}^6$
