Help what polynomials are there??

Mathematics
1 answer:
N76 [4]3 years ago
8 0

Answer:

All of them are polynomials except c.

Step-by-step explanation:

Polynomials are in the form:

a_0+a_1x+a_2x^2+a_3x^3+a_4x^4+a_5x^5+a_6x^6+\cdots +a_nx^n

You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...

We also don't have division by a variable.  All the exponents are whole numbers.

a) While it has a square root, it is not on a variable so a is a polynomial.  The exponents on the variables are whole numbers.

b) b is a polynomial also because all the exponents are whole numbers.

c) This is not a polynomial because there is a square root on a variable.

d) This is a polynomial.  All the exponents are whole numbers.

Can you simplify 37/80
Setler [38]

Answer:

Step-by-step explanation:

37 is prime, so it's not possible to reduce/simplify 37/80.  37/80 is the ratio of two integers.  We could, of course, use a calculator to find the decimal equivalent:  0.4625, but this is not more accurate than the ratio 37/80.
