When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.
We need to use the calculator, using the tan⁻¹ function:

Using the calculator:

To the nearest tenth:
