Option A is the correct option. The polynomial correctly combines the like terms and expresses the given polynomial in standard form is,
f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶
<h3>What is the polynomial equation?</h3>
A polynomial equation is an equation in which the unknown variable is one and the highest power of the unknown variable is n. Here n can be any real number.
Given information-
The polynomial equation given in the problem is,
8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³
Let the above polynomial is. Thus,
f(m,n) = 8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³
The terms with the same base and exponents can be added or subtracted from each other. Thus solve the equation further as,
f(m,n) = ( 8mn⁵ - mn⁵ ) -2m⁶ + ( 5m²n⁴+9m²n⁴ ) - ( m³n³-4m³n³) + n⁶-4m⁶
f(m,n) = 7mn⁵ - 2m⁶ + 14 m²n⁴ - 5 m³n³ + n⁶- 6m⁶
Arrange it as,
f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶
Thus the polynomial correctly combines the like terms and expresses the given polynomial in standard form is,
f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶
