Because the rout mean pow(1/2)
And root root mean pow(1/3)
And if you multiply pow(1/3) with pow(3)
It’s will give you pow of 1 as we want x in
Part A:
Given
defined by
but
Since, f(xy) ≠ f(x)f(y)
Therefore, the function is not a homomorphism.
Part B:
Given
defined by
Note that in
, -1 = 1 and f(0) = 0 and f(1) = -1 = 1, so we can also use the formular
and
Therefore, the function is a homomorphism.
Part C:
Given
, defined by
Since, f(x+y) ≠ f(x) + f(y), therefore, the function is not a homomorphism.
Part D:
Given
, defined by
but
Since, h(ab) ≠ h(a)h(b), therefore, the funtion is not a homomorphism.
Part E:
Given
, defined by
, where
denotes the lass of the integer
in
.
Then, for any
, we have
and
Therefore, the function is a homomorphism.
so heres how you do this
28/7=4 kilograms lost each day
now convert the 4 kilograms to pounds
4 x 2.2 = 8.8 pounds lost each day is your answer
add me as a friend if you like im good at math
V=LWH
V=4*4*8
V=128
answer is 128 ft^3
128 cubic feet
Yea thats the coordinate plane good job
