Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is .
So the side is 1.0 inch in, the surface area is square inches.
In Linear approximation means you ignore the term , if
is a small number, because then
will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here,
The error in the area is approximately,
So the error is 0.012.
If is a number that is both divisible by 4 and 5, then
4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that is a solution to the system, where
is any integer. Simply put, any multiple of 20 fits the bill.
Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have when
, so the sum we want to compute is
Rational exponents
work like this: the numerator is the actual exponent of the base, while the denominator is the index of the root.
In other words, we have
So, in you case, we have
Assuming that the question contanis a typo. If you actually mean ,
then you can write it as
