hi
im doing a course in complex maths for the building industry and have to pass this maths section before i go on. maths was a bad subject for me so now i need to learn. my biggest problem is notation such as one question is
convert 39cm to km and answer in scientific notation
would that be 100000cm = 1km therefore 39/100000=0.00039
is that right
and the one thats got me is
a mass rests on an area of 80mm2 and exerts a force of 320 kg m/s2. express the pressure exerted on this area in kN/cm2
i worked it out but not sure if im right
so can you all help me out i will post more soon
cheers dan
