The answer is like terms.
So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:

In short, your simplified expression is going to be -16x^7y^6.
Answer:
42.50/5 = p is the equation; $8.50 per pack
Step-by-step explanation:
DIVIDE 42.50 between the 5 packs of toilet paper.
THIS GETS YOU $8.50 per pack.
THE EQUATION used was 42.50/5 = p.
(–23) – 45 – (–98) =–23 – 45 +98=-68+98=30
As a group they were paid $1000 after putting in 4+6+5+5 = 20 worker-hours.
$1000/(20 worker-hours) = $50/(worker-hour)
Alemu received 4*$50 = $200
Tulu received 6*$50 = $300
Kassa and Tegitu each received 5*$50 = $250
