(a)
Interpretation:
The number of places does decimal have to be moved to express the number in standard scientific notation should be determined along with identify whether the exponent of the power of 10 is positive or negative.
Concept Introduction:
Scientific notation for a number is written in such a way that large numbers are written in small decimal form which is then multiplied by the power of 10.
For numbers less than 1, the power of 10 in scientific notation has negative exponent and for numbers greater than 1, the power is either zero or has positive exponent.
Answer to Problem 116AP
