Answer:
531,441·g^6·h^8
Step-by-step explanation:
The operative rule of exponents is ...
(a^b)^c = a^(b·c)
Working from the inside out, according to the order of operations, we get ...
= (9^3·g^3·h^4)^2
= 729^2·g^(3·2)·h^(4·2)
= 531,441·g^6·h^8
Answer:
120° and 240°
Step-by-step explanation:
The given info about the angle x is cos x = - 1/2.
By definition, cos x = - 1/2 = (adjacent side) / hypotenuse, so here we can assume the adjacent side is -1 and the hypotenuse is 2.
A negative cosine tells us that the angle is in Quadrant II or Quadrant III.
If x is in Quadrant II, then its value is 120°
If x is in Quadrant III, then its value is 120° + 120°, or 240°
