Answer:

  20x^26

Step-by-step explanation:

The leading term is the one with the highest degree.

In the expansion of (x-2)^15, that will be x^15.

In the expansion of (4-x)^11, that will be (-x)^11 = -x^11.

So, the leading term of the product is ...

  (-20)(x^15)(-x^11) = 20x^26

__

In the attached, terms are listed in order of increasing degree, so the "leading" term appears last.

Answer:   20x^26

============================================

Work Shown:

The leading term for (x-2)^15 is x^15

The leading term for (4-x)^11 is -x^11

Multiply the outer value -20 with each of those leading terms to get

-20*x^15*(-x^11)

20x^(15+11)

20x^26

which is the leading term of -20(x - 2)^15 (4-x)^11
