Answer :

The answer is: The given numbers in scientific notation are

1.  4.0×[tex]10^5[/tex]

2. -4.0×[tex]10^9[/tex]

3. 7.3×[tex]10^{-7}[/tex]

4. 1.70× [tex]10^{-3}[/tex]

5. 8.675309×[tex]10^2[/tex]

6. - 1.23×[tex]10^{-4}[/tex]

Scientific notation is a way of representing very large or very small numbers in a simpler form.

How to write a number in scientific notation?

  • Scientific notation helps represent very large or very small numbers by taking a single digit and raising 10 to an exponential power.
  • The exponent is positive for very large numbers and negative for very small numbers.
  • A common expression for scientific notation is:

a×[tex]10^b[/tex] ; 1≤a≤10

  • Now, given numbers are written in scientific notation by adjusting their decimal points or adding a new point with the 10 raised to the exponential power as-

1. 4.0×[tex]10^5[/tex]

2. -4.0×[tex]10^9[/tex]

3. 7.3×[tex]10^{-7}[/tex]

4. 1.70× [tex]10^{-3}[/tex]

5. 8.675309×[tex]10^2[/tex]

6. - 1.23×[tex]10^{-4}[/tex]
