@kropot72 i just checked my answer but the answer seem to be wrong... I got a hint saying. Any thought?

Problem is failure to read the problem carefully.  The problem requests the answer in mega ohms!

kropot72 · Answer

@adunb8 My result posted above (rounded) is 1.554 mega ohms.

whpalmer4 · Answer

Yep, @kropot72 you gave the correct answer (which can be verified by looking at the voltage drop across that proposed resistance with the current given).  Not your responsibility to type in the answer in the correct units, even though you gave them :-)
