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
Answer:
q = ± p/2
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
= q² ( take the square root of both sides )
± = q p/2
