Im in the dark. how do you solve a problem with a long exponent, such as (-18)^4521 without a calculator ? :-(

You just... don't. Even that would be a miracle for a calculator to accomplish!
Well you can get a good approximation with a scientific calculator or a table of logs.You just... don't. Even that would be a miracle for a calculator to accomplish!
\(\displaystyle x = (-18)^{4521} \implies -x = 18^{4521}> 0 \implies log_{10}(- x) = 4521 * log_{10}(18) \approx 5675 \implies - x \approx 10^{5675} \implies x \approx - 10^{5675}\).

Hello, flowerfalcon!
Please state the original problem.
I'm sure they don't want the actual answer.
. . It has over 5,600 digits.
A typical problem might ask for the last digit.
