HELLO DEAR
IF RESULT IS nu WHERE u is unit , as result is expressed in a different unit so only value of u changes
for e.g. when we write n metre here metre is unit, but when unit is changed for e.g.n centimeter so only unit is affected but it has effect on whole answer.
if answer is still unclear please post your query
thanx and if you are able to understand please approve my answer
