Scientific notation with negative powers of 10 worksheet - Answers
Question 1 :
Write the given number in scientific notation.
0.00006
Answer :
Here decimal point comes first at non zero digit comes next.
We have to move the decimal point to the right.
No. of digits from decimal point up to the first non zero digit = 5
So, the decimal point has to be moved 5 digits to the right and exponent of 10 should be -5 (negative integer)
Hence, 0.00006 = 6 x 10⁻⁵
Let us look at the next problem on "Scientific notation rules".
Question 2 :
Write the given number in scientific notation.
0.000216
Answer :
Here decimal point comes first and non zero digit comes next.
We have to move the decimal point to the right.
No. of digits from decimal point up to the first non zero digit = 4
So, the decimal point has to be moved 4 digits to the right and exponent of 10 should be -4 (negative integer)
0.000216 = 2.16 x 10⁻⁴
Hence, 0.000216 = 2.16 x 10⁻⁴
Question 3 :
Write the given number in scientific notation.
0.0000009
Answer :
Here decimal point comes first and non zero digit comes next.
We have to move the decimal point to the right.
No. of digits from decimal point up to the first non zero digit = 7
So, the decimal point has to be moved 7 digits to the right and exponent of 10 should be -7 (negative integer)
0.0000009 = 9 x 10⁻⁷
Hence, 0.0000009 = 9 x 10⁻⁷
