Answer:
Step-by-step explanation:
For a negative exponent you always flip the number so instead of 
it would be 
and 5 to the first power is 5
Now for 
any exponent with a zero it always equals 1
So 
Hope this helps!
The figure is a right triangle so we can use the Pythagorean theorem to find the third side AKA the hypotenuse.
Pythagorean theorem = a² + b² = c² where A and B are the legs of the triangle and C is the hypotenuse.
39² + 80² = c²
169 + 6400 = c²
6569 = c²
Square root both sides to cancel out the squared variable.
√6569 = √(c²)
√6569 = c
The third side, the hypotenuse, is √6569 units long.

Answer:
2
Step-by-step explanation:
Let x = number of items Steve sells
Let y = salary earned
Create two equations:
Vacuum sales: y = 500 + 100x
Encyclopedia sales: y = 300 + 200x
Equal the equations and solve for x to find the number of items Steve needs to sell for the two salaries to be the same:
500 + 100x = 300 + 200x
Subtract 300 from both sides: 200 + 100x = 200x
Subtract 100x from both sides: 200 = 100x
Divide both sides by 100: 2 = x
Therefore, Steve would have to sell 2 items for the two salaries to be the same.
