I suppose you mean

Differentiate one term at a time.
Rewrite the first term as

Then the product rule says

Then with the power and chain rules,

Simplify this a bit by factoring out
:

For the second term, recall that

Then by the chain rule,

So we have

and we can simplify this by factoring out
to end up with

1.25x2=2.50
2.50x2=5.00
Total-7.50
20.00-7.50=12.50
Answer:
16x16+14−99x8
=16x16+14+−99x8
Answer- =16x16−99x8+14
sooo its -522
