2x^4-y
6 + w
y^2-^3 sqrt y + 4

Answer 1

Answer 2

6+w has whole number powers, doesn't it.

6w^0+w^1

Answer 3

yes

Answer 4

and 2x^4-y^1 also has whole number powers....

Answer 5

yeah

Answer 6

now, do the rest of your options (write the powers)

Answer 7

y^2-^3 sqrt y + 4^1 Like that?

Answer 8

but that term sqrt(y) also has a power.

Answer 9

\(\large\color{black}{ \displaystyle \sqrt[3~]{y~} =\sqrt[3~]{y~^{1}}=y^{1/3} }\)

Answer 10

is 1/3 a whole number ?

Answer 12

so the correct answer would be D because 1/3 is not a whole number and the rest have whole numbers in them.
