Question

Which polynomial is in standard form? 2xy^3 +3x^3 y^4 -4x^4 y^5 +9x^5 y^6 Which polynomial is in standard form?

Answer 1

Answer:

(D) $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

Step-by-step explanation:

A polynomial is said to be in standard form when it is arranged in descending powers of x.

When there are more than one variable, the alphabetical order is followed. For example, if there are variables x and y in the polynomial, x must be in descending order and y will be in ascending order.

From the given options, the polynomial which is in standard form is:

$5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

The correct option is D.
