What is the value of the expression (–3)4? A. –12 B. –81 C. 81 D. 12

Hi! Just for your future reference, a lot of people on the internet (not even just OpenStudy) type that as (-3)^4, where the "^" indicates "to the power of." And, if you put it in `\( \)` on OpenStudy, it does this! \((-3)^4\) Any way, I'll teach you a good way to think about it. I mean, you can just put it in a calculator. But there's really a pattern. Consider \((-1)\). That is \((-1)^1\). What about \((-1)^2\)? \(-1\dot\ -1=1\) Actually, any even power will have the negatives cancel like that. So, \((-3)^4\) will be positive. It will be \(3^4\).
thanks
\((-1)=-1\\ (-1)(-1)=1\\ (-1)(-1)(-1)=-1\\ (-1)(-1)(-1)(-1)=1\\ (-1)(-1)(-1)(-1)(-1)=-1\)
Anything to the zero equals 1, so \((-1)^0=1\), too.
i think its 12
but not really sure
It is 12! :)
\((-3)^4=3^4\) However.... Watch out. Odd powers will stay odd! Example:\(\quad(-3)^3=-(3^3)\)
thank you
You're welcome!
Take care!
