nice algebra problem
3√x = 5x (squaring both side)9x = 25x²25x² - 9x = 0x(25x - 9) = 0So, x = 0 or 25x - 9 = 0Or x = 9/25
Is this the junior Olympiad? Seems very easy for an Olympiad problem.
25x^2=9xDeviding both sides by x we have25x=9x =9/25 answer.
That's what I saw, too. But it doesn't give you zero as an answer -- and it is one.
Bro you can't divide by x if you are not sure that x does not equal 0.... for the fact, x1=9/25 but x2=0. For that reason you definitely can't divide by 0
@@vasilizrl9125 Well, it did produce a verifiable answer though.
25х^2=9х (divide both sides by x)25х=9х=25/9.
The problem with that solution is that you don't know if x=0 so you cannot just divide by it (btw there are 2 solutions x1=9/25 and x2=0).
Please i have a question in image how can you help me solve please
Please how do I get the question to you
x=9/16=0.5625
