Question

*8√y² - 7xy -23 is a polynomial or not?*
​

Answer 1

Answer:

The required answer is No.

Step-by-step explanation:

Given: $8\sqrt{y} ^{2}- 7xy -23$

To find: polynomial or not.

Solution:

Exponents that are negative or fractional are not allowed in polynomials. Denominator-level variables Polynomials do not permit variables under a root. The polynomial does not make use of any special characteristics, such as trig functions, absolute values, logarithms, etc.

Rules to Determine Whether an Expression Is Polynomial:

• A polynomial is a combination of terms that are isolated using + or signs. Any of the following may be excluded by polynomials:
• Negative or fragmented types are not permitted in polynomials.
• Factors that affect the numerator.
• In polynomials, factors below a root are not allowed.
• The polynomial does not make use of special elements like trig powers, absolute qualities, logarithms, and so forth.
• Constants, factors, and types can all exist in polynomials, but variable division is never one of them.

$8\sqrt{y} ^{2}- 7xy -23$ is not a polynomial because polynomials are not allowed to have factors below a root.

Hence, The answer is No.
