Answer:
Because 0 at end after decimal has no value.
Step-by-step explanation:
Given : Tony's calculator correctly shows
To find : Explain why the number of decimal places in the product is not the same as the number of decimal places in the two factors ?
Solution :
3.4 has 1 number in the decimal place
0.5 has 1 number in the decimal place
So, total we have 2 decimal place
i.e.
But in 1.70 the 0 at end after decimal has no value so we write it as 1.7.
that's why the number of decimal places in the product is not the same as the number of decimal places in the two factors.

The characteristic of an exponential parent function in the options.
To find:
Which is not a characteristic of an exponential parent function?
Solution:
The exponential parent function is:
Where, .
At ,
It means the function passes through the point (0,1) but it does not passes through the origin. So, the statement in option A is true but the statement in option C is false.
The domain of the exponential parent function is all real numbers and the range is positive real numbers (y > 0). So, the statements in the options B and D are true.
Therefore, the correct option is C.
