Actually Welcome to the Concept of the Inverse Trigonometry Function.
So here, we get as
SinX = 1/2
X = Sin^-1(1/2)
X= 30°
when you multiply exponents, they add together and the base will remain the same:
-5+-2
=-7
therefore the answer is 8^-7
to get rid of the negative, flip the fraction so it becomes
1/8^7
Is what is an inequality your question? An inequality is basically expressions that use the "greater than", "less than", "greater than or equal to", or "less than or equal to" symbols. A.K.A these: > < ≥ ≤
