3√x + 8 = 10√x + 9
This is how i solved it:
subtract 3√x from both sides,so the result is:
8 = 7√x + 9
subtract 9 from both sides
-1 = 7√x
after that,everything gets squared:
1 = 49 x
and then,divide everything by 49,so:
1/49 = x
HOWEVER,there must be something wrong,cause the above equation has no solutions,due to the fact that the response should be negative.
But mine,obviously has a solution....What am i doing wrong?
