document.write( "Question 548289: So I have a question i'm doing pre-algebra and i'm having a little trouble so the question is 3m over 15m to the third power and in my book it says something like take the top variable subtracted (-) by the bottom variable and usually if its like m we just make it m to the first power but in the book it shows the bottom number (15) as a one (1) well the problem in the book is 5 to the 6th power over 5 to the 8th power and it takes 6-8 and gets -2 so its 5 to the -2nd power over 5 and it changes it to 1 over 5 to the 2nd power and i'm not sure if everyone of the bottom numbers should be changed to 1 or not so yea I tried it and i'm confused and I did all of the other ones and I think I got them right but i'm just stumped by this one and I've tried and tried but i'm stuck so yea please help me. Wow that was a really long run on sentence but yea thanks. \n" ); document.write( "

Okay I think what you are asking is to simplify \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "We have an exponent rule that says something like this: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So all we are doing is using this and a few other tricks \n" ); document.write( " \n" ); document.write( "can be broken up as follows \n" ); document.write( " \n" ); document.write( "Now 3/15=1/5 \r \n" ); document.write( "\n" ); document.write( "and \n" ); document.write( " \n" ); document.write( "and using the rule above this is just \n" ); document.write( "\n" ); document.write( "So from \n" ); document.write( " \n" ); document.write( "we get \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "We could also use the rule \n" ); document.write( " \n" ); document.write( "to write our answer as \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hopefully this helps, please let me know if you are unsure:) \n" ); document.write( " \n" ); document.write( " |
