0.00006
Problem 2 :
Write the given number in scientific notation.
0.000216
Problem 3 :
Write the given number in scientific notation.
0.0000009

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
