Answer:
x = 7
y = 5
Step-by-step explanation:
The applicable rule of exponents is ...
a^-b = 1/a^b
__
For a=-j and b=7,
(-j)^-7 = 1/(-j)^7 ⇒ x = 7
For a=k and b=-5,
k^-5 = 1/k^5 ⇒ y = 5
So for this you will be doing proportions. Your equation will look like this:
Firstly, cross multiply:
Next, square root both sides of the equation, and your answer should be
I don't believe you can. It would end up being 1/2 for all the terms so just leaving it as a fraction would be neater.
