How to tell if an expression is a polynomial?

1 answer:

3 0

If it has more than one term (if there is a plus or minus sign when the equation is at its simplest form)

2x = no

2x^(2) = no

2x + 5x = no

2x^(2)+5x^(2) = no

2x^(2)+5x = yes

2x^(3)+5x^(2)+2x = yes

geniusboy [140]

Answer:

Step-by-step explanation:

(1)

a1=-2

r=-2

$a_{20}=(-2)(-2)^{20-1}=-2(-2)^{19}=2^{20}=1048576\\(2)\\a_{1}=1000\\r=\frac{200}{1000} =\frac{1}{5} \\a_{8}=1000(\frac{1}{5} )^{8-1}=1000(.2)^7=0.0128\\(3)\\a_{1}=2\\a_{3}=50\\a_{2}=\sqrt{2*50} =10\\r=\frac{10}{2} =5$
