Algebra.Com's Answer #10962 by ilana(307) ![]() You can put this solution on YOUR website! Actually, you are making this much more difficult than necessary. 4^x is just a term, so pretend it's 4x for now. Then we have 4x+6=7. You then subtarct 6 from both sides to get 4x=1, so x=1/4. In your problem, begin the same way but get 4^x=1. (Any number)^0=1, so x=0. \n" ); document.write( " |
