Ok, so let’s take the given phrase.
Eight more than the product of 3 and a number is -13. A translation to numbers looks like this:
3x + 8 = -13
Now, let’s solve for x. We can start the process by subtracting 8 from both sides.
3x = -21
now, we will divide each side by 3 to isolate the variable, thus solving for x.
x = -7
Use the difference of 2 squares (a - b)(a + b) = a^2 - b^2:-
(x - 1/x)(x + 1/x) = x^2 - (1/x)^2
= x^2 - 1/x^2
(x ^2 - 1/x^2)(x^2 + 1 /x^2)
= x^4 - 1/x^4
(x^4 - 1/x^4)(x^4 + 1/x^4)
= x^8 - 1 /x^8 Answer
