What is 000435 in scientific notation?

Answer 1

First you have to identify the significant figures. Non-zero digits are always significant, but zeroes are significant depending on where they are located. In 000435, you have 3 leadingzeroes in front of 435. Leading zeroes are neversignificant, so you are left with 435 as significant digits. Now we can convert to scientific notation.

Write the first number 4, then a decimal, then the remaining 2 significant digits.

4.35

Now to get back to 435, we need to multiply 4.35 by 10 to get 43.5, and then once again to get 435. This is represented by 10 to the power of 2, 10^2.

The final outcome is 4.35 X 10^2
