# SCIENTIFIC NOTATION WITH NEGATIVE POWERS OF 10 WORKSHEET

Scientific Notation with Negative Powers of 10 Worksheet :

Worksheet given in this section will be much useful for the students who would like to practice problems on scientific notation with negative powers of 10.

## Scientific Notation with Negative Powers of 10 Worksheet - Problems

Problem 1 :

Write the given number in scientific notation.

0.00006

Problem 2 :

Write the given number in scientific notation.

0.000216

Problem 3 :

Write the given number in scientific notation.

0.0000009

Problem 4 :

The average size of an atom is about 0.00000003 centimeter across. Write the average size of an atom in scientific notation. ## Scientific Notation with Negative Powers of 10 Worksheet - Solutions

Problem 1 :

Write the given number in scientific notation.

0.00006

Solution :

In the given number, number of digits from decimal point up to the first non zero digit is 5.

So, the decimal point has to be moved 5 digits to the right and exponent of 10 should be -5 (negative integer).

Therefore,

0.00006  =  6.0 x 10-5

Problem 2 :

Write the given number in scientific notation.

0.000216

Solution :

In the given number, number of digits from decimal point up to the first non zero digit is 4.

So, the decimal point has to be moved 4 digits to the right and exponent of 10 should be -4 (negative integer).

Therefore,

0.000216  =  2.16 x 10-4

Problem 3 :

Write the given number in scientific notation.

0.0000009

Solution :

In the given number, number of digits from decimal point up to the first non zero digit is 7.

So, the decimal point has to be moved 7 digits to the right and exponent of 10 should be -7 (negative integer).

Therefore,

0.0000009   =  9.0 x 10-7

Problem 4 :

The average size of an atom is about 0.00000003 centimeter across. Write the average size of an atom in scientific notation.

Solution :

In 0.00000003, number of digits from decimal point up to the first non zero digit is 8.

So, the decimal point has to be moved 8 digits to the right and exponent of 10 should be -8 (negative integer)

0.00000003  =  3.0 x 10-8

Therefore, the average size of an atom in scientific notation is about

3.0 x 10-8 centimeter across After having gone through the stuff given above, we hope that the students would have understood how to do problems on scientific notation with negative powers of 10.
