the problem is: evaluate: 32^-3/5 =1/32^3/5 =??? 1/8 ? thus my original question: without a calculator, how do i Know that 32^3/5 = 8 ...okay, find the fifth root of 32 and cube it, gotcha
If you want to be fancy This does not require a calculator at all! (take the log of both sides) log base change formula. (changes and base to two base 10 logs): and ((This is my 100th post! Whooo! ))
