Answer:
a x^2/2 is a polynomial because the power of x is 2 which is a positive whole number but 2/x^2 is not a polynomial because the power of x is -2 which is negative whole number.
b.in

the power if x will be

which is not a whole number so it is not a polynomial.
but in

the power if x is a positive whole number.so it is a polynomial.
c.the greatest power of variable of the term is called degree of polynomial
Answer:
9/16
Step-by-step explanation:


Derivative rule:


Here, n=-1, so

Evaluating this at x=-4 gives 9/16
I used math
anyway
remember you can do anything to an equation as long as you do it to both sides
so
4n+2 and 1/2=2n+5
minus 2n both sides
4n-2n+2 and 1/2=2n-2n+5
2n+2 and 1/2=0+5
2n+2 and 1/2=5
minus 2 and 1/2 both sides
2n=2 and 1/2
divide both sides by 2
I mean times both sides by 1/2
n=1 and 1/4
answer is C
Hello,
√6.25 =2.5
but √36=6
1626 divided by 1 very simple just put that :D
