Complexity=3, Mode=toNormal

Convert from scientific notation into normal notation.
#ProblemCorrect AnswerYour Answer
18.39 × 106
Solution
Significant value = 8.39
Exponent = 6
Must move the decimal point 6 places to the right
You should end up with 8390000
#ProblemCorrect AnswerYour Answer
25.86 × 108
Solution
Significant value = 5.86
Exponent = 8
Must move the decimal point 8 places to the right
You should end up with 586000000

Complexity=4, Mode=toScientific

Convert from normal notation into scientific notation. Use '*' for the multiplication sign.
#ProblemCorrect AnswerYour Answer
16.357
Solution
Begin by finding out the significant part of the number. It should always be between 1 and 10. Thus, the significant part is 6.357
Must move the decimal 0 spots to the left to end up with the significant value. Thus, the exponential power should be 0.
Scientific Notation = significant value × 10exponent = 6.357*10^0
#ProblemCorrect AnswerYour Answer
20.000000002567
Solution
Begin by finding out the significant part of the number. It should always be between 1 and 10. Thus, the significant part is 2.567
Must move the decimal 9 spots to the right to end up with the significant value. Thus, the exponential power should be -9.
Scientific Notation = significant value × 10exponent = 2.567*10^-9
