Formula used

Scientific notation = a × 10ⁿ, where 1 ≤ |a| < 10 and n is the integer power of ten. For nonzero x: n = floor(log10(|x|)) and a = x ÷ 10ⁿ.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Check the exponent and keep the original value visible before copying the notation into homework, lab notes or spreadsheets.

Zero is handled as 0 × 10⁰ because it has no unique nonzero scientific-notation coefficient.
The coefficient is rounded only for display; the exponent is chosen from the unrounded absolute value.
Negative numbers keep their minus sign on the coefficient.
This is arithmetic notation, not a measurement-uncertainty or significant-figures standard unless your worksheet or lab instructions say so.

Master’s Tip

How to use the result well

Master’s Tip: keep the original decimal number on the report beside the scientific notation. That prevents a copied exponent or rounded coefficient from becoming detached from the value it represents.

Method

Scientific notation = a × 10ⁿ, where 1 ≤ |a| < 10 and n is the integer power of ten. For nonzero x: n = floor(log10(|x|)) and a = x ÷ 10ⁿ.

For 1,230,000 with 3 decimal places: log10(1,230,000) is between 6 and 7, so n = 6. Then 1,230,000 ÷ 10⁶ = 1.23, giving 1.230 × 10⁶ when shown to 3 decimal places.

Assumptions

Zero is handled as 0 × 10⁰ because it has no unique nonzero scientific-notation coefficient.
The coefficient is rounded only for display; the exponent is chosen from the unrounded absolute value.
Negative numbers keep their minus sign on the coefficient.
This is arithmetic notation, not a measurement-uncertainty or significant-figures standard unless your worksheet or lab instructions say so.
