Question

Write 753 in scientific notation ?

Answer 1

The given number is

`753`

We want to write this number in scientific notation.

To convert the number into the scientific notation we shift the decimal point towards left until one decimal digit is left.

This could be best understood with the help of a few examples.

Example:

Let's say the number is 4000.

Now shift the decimal point to the left so that only the digit 4 is left.

`4.0x10^3`

Since we shifted the decimal point towards left by 3 points that's why we raised the power of 10 to 3 times.

Now let's come back to 753.

Now shift the decimal points towards left by 2 points so that only 7 digit is left

`7.53x10^2`

Since we shifted the decimal point towards left by 2 points that's why we raised the power of 10 to 2 times.

If you multiply 7.53 with 10² then you will get 753.
