Answers

Complexity=3, Mode=toNormal

Convert from scientific notation into normal notation.

#	Problem	Correct Answer	Your Answer
1	6.05 × 10^-10
Solution Significant value = 6.05 Exponent = -10 Must move the decimal point 10 places to the left You should end up with 0.000000000605

#	Problem	Correct Answer	Your Answer
2	1.4 × 10^-2
Solution Significant value = 1.4 Exponent = -2 Must move the decimal point 2 places to the left You should end up with 0.014

Complexity=4, Mode=toScientific

Convert from normal notation into scientific notation. Sample answer: 4.5 × 10⁶. Type: 4.5 * 10^6.

#	Problem	Correct Answer	Your Answer
1	2223000000
Solution Begin by finding out the significant part of the number. It should always be between 1 and 10. Thus, the significant part is 2.223 Must move the decimal 9 spots to the left to end up with the significant value. Thus, the exponential power should be 9. Scientific Notation = significant value × 10^exponent = 2.223*10^9

#	Problem	Correct Answer	Your Answer
2	0.000007505
Solution Begin by finding out the significant part of the number. It should always be between 1 and 10. Thus, the significant part is 7.505 Must move the decimal 6 spots to the right to end up with the significant value. Thus, the exponential power should be -6. Scientific Notation = significant value × 10^exponent = 7.505*10^-6
