Answer 1

Dear student,

0.0000043 m = 4.3 x 10-6 m

Explanation:-

Scientific notation is a number which is express in the format of x∗10y in which x is between one and ten and y is an integer value.

For value of x take the first non-zero digit (i.e 4) as the ones place. All subsequent digits fall into the tenths, hundredths, etc. places.

x=4.3

To find y, we must count the number of places that x is removed. In 0.0000043 , the first digit of x is in the lakhs place. This indicates that y will be −6.

The final scientific notation will be 4.3x 10-6 m.

Therefore option B is correct answer.

Please give positive rating to this answer.
