Question

The scientific notation for $700$ is_______________.

Answer 1

Scientific notation:

1. Scientific notation is used to represent extremely large or extremely small numbers by multiplying a single-digit integer by $10$ raised to the power of the exponent.
2. If the number is very large, the exponent is positive; if the number is very small, the exponent is negative.
3. Given number is $700$
4. It can also be written as $700.0$
5. Move the decimal point to the left of $700.0$ up to $2$ places.
6. To make the number $7.0$, the decimal is shifted two positions to the left.
7. We use a positive exponent here since the values are greater than 10 and the decimal is moved to the left.

$\Rightarrow 700=7\times {10}^2$

Hence, the scientific notation for 700 is 7 x 10².
