`(a1/2) 1/2 (ab1/2)`
`therefore (a/2)times 1/2 times ((ab)/2)`
Note how effectively you are multiplying `a/1 times1/2 and (ab)/1 times 1/2`
Now multiply everything:`therefore a/2 times1/2times(ab)/2` becomes `(a times1 timesab)/(2 times2 times2)`
`therefore = (a^2b)/8` (remember 2^3 is 8)
therefore =`( a^2b)/8`
