If #2^x xx4^(x+1)=8# what is the value of #x#?
High detail using first principles. Plus an alternative approach for the end.
But 4 is
Divide both sides by 4
You can solve directly from the above but I wish to demonstrate an alternative approach that could prove useful in different circumstances:
take loges of both sides remembering that
Divide both sides by
divide both sides by 3
