√20=√2×2×5=2√5 , √40=√2×2×10=2√10 , √80=√4×4×5=4√5
√10+√20+√40-√5-√80=√10+2√5+2√10-√5-4√5=3√10-3√5=3(√10-√5)
15/(√10+√20+√40-√5-√80)=15/3(√10-√5)=5/(√10-√5)
=5/(3.162-2.236)=5/2.926=1.708(Ans.)
√10+√20+√40-√5-√80=√10+2√5+2√10-√5-4√5=3√10-3√5=3(√10-√5)
15/(√10+√20+√40-√5-√80)=15/3(√10-√5)=5/(√10-√5)
=5/(3.162-2.236)=5/2.926=1.708(Ans.)
