Question

How do you write 1,263 in scientific notation?

Answer 1

`1.263 xx 10^3`

Explanation:

to express a number in scientific notation it has to be expressed in the form `a xx 10^n`

where 1 ≤ a < 10 and n is an integer

rewrite 1263 as a number between 1 and 10 ie. 1.263 and to get it equal to it's original value we have to multiply by 1000

so 1263 = `1,263 xx 10^3`
