Is the expression 8%2F%28w-1%29 or is it 8%2Fw-1 ???



8%2F%28w-1%29 is undefined when the denominator w-1 is zero. So set the denominator equal to zero and solve for 'w' to get w-1=0 ----> w=1


So 8%2F%28w-1%29 is undefined when w=1


--------------------------------


8%2Fw-1 is undefined when the denominator w is zero. So set the denominator equal to zero to get w=0


So 8%2Fw-1 is undefined when w=0
