Since the question actually asks where the left side IS NOT EQUAL to 8

The answer is actually

All real x EXCEPT x=8

Have a look at this site.

Edited:  Thank you Chris, I can see where you get that from. I guess I did not give enough thought to the wording of the question.

The very first anonymous gave the BEST answer to this question.

I cut and pasted the exact question into the calculator.

It may not be the intended question but it is the question that was asked!

People should learn to use brackets properly and ask the question that they intend.

$$\left(\dfrac{x}{2^4}\right)^{-5}\\\\\\
=\left(\dfrac{2^4}{x}\right)^{5}\\\\\\
=\dfrac{2^{20}}{x^5}\\\\$$

Your question doesn't make sense because your expression only has numbers in it.  It has no letters so it cannot be a function.  There is nowhere to sub  x=anything in because there is no x!

This is the value of the numerical expression.   

$${\frac{\left({\mathtt{\,-\,}}{{\mathtt{1.001}}}^{{\mathtt{6}}}{\mathtt{\,-\,}}{\mathtt{1}}\right)}{\left({\mathtt{\,-\,}}{{\mathtt{1.001}}}^{{\mathtt{3}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right)}} = {\mathtt{668.003\: \!447\: \!223\: \!296\: \!296\: \!3}}$$

You take the first non zero digit.  That is 1

then you take the second digit. that is 0

then you use the 3rd one for rounding. It is 7 which is bigger so the 0 goes up to 1

So you have 11 but you need to add a non significant 0 to make the place value correct.

Ans: 110

on the forum calc you use asin   

asin is the same as sin-1

1/12*100add the percent sign afterwards

now do it on the calc on the home page.
