Answer:
Step by Step Solution (A):
Given Input Number : NaN
= N * 1
= N * 1
= ( ) * 1
= 0 x 10NaN
Step by Step Solution (B):
Given Input Number : 75
= 7 * 10 + 5 * 1
= 7 * 10 + 5 * 1 * ( 10 / 10 )
= ( 7 + 0.5 ) * 10
= 7.5 x 101
Step by Step Solution (C):
Given Input Number : 25000017
= 2 * 10000000 + 5 * 1000000 + 0 * 100000 + 0 * 10000 + 0 * 1000 + 0 * 100 + 1 * 10 + 7 * 1
= 2 * 10000000 + 5 * 1000000 * ( 10 / 10 ) + 0 * 100000 * ( 100 / 100 ) + 0 * 10000 * ( 1000 / 1000 ) + 0 * 1000 * ( 10000 / 10000 ) + 0 * 100 * ( 100000 / 100000 ) + 1 * 10 * ( 1000000 / 1000000 ) + 7 * 1 * ( 10000000 / 10000000 )
= ( 2 + 0.5 + 0 + 0 + 0 + 0 + 0.000001 + 7e-7 ) * 10000000
= 2.5 x 107
Step by Step Solution (D):
Given Input Number : 20719000
= 2 * 10000000 + 0 * 1000000 + 7 * 100000 + 1 * 10000 + 9 * 1000 + 0 * 100 + 0 * 10 + 0 * 1
= 2 * 10000000 + 0 * 1000000 * ( 10 / 10 ) + 7 * 100000 * ( 100 / 100 ) + 1 * 10000 * ( 1000 / 1000 ) + 9 * 1000 * ( 10000 / 10000 ) + 0 * 100 * ( 100000 / 100000 ) + 0 * 10 * ( 1000000 / 1000000 ) + 0 * 1 * ( 10000000 / 10000000 )
= ( 2 + 0 + 0.07 + 0.001 + 0.0009 + 0 + 0 + 0 ) * 10000000
= 2.0719 x 107
Step-by-step explanation:
Writing numbers based on powers of ten is called exponential notation. It simplifies numbers by getting rid of zeros, and making math easier. It is a number notation which is the product of the number with the power of 10's. Exponential notation lets you move the decimal point in a number.
