I have this problem to simplify with positive exponents:
So, working with the interior brackets, I applied -3 to the equation, which resulted in:
**because "-4" was not in brackets, the exponent was applied to the 4 only, independent of the negative sign, which resulted in -(-64), so:
which resulted in this insane answer:
However, when I checked it, an online calculator said the answer was:
which means that when applying exponents to the number I did something wrong, as it should have ended up negative, which would have resulted in it becoming a positive denominator.
What did I do wrong to end up with the wrong sign on that number?
