Answer 1

8.28×（6.5一3.9）+2.6×1.72
=8.28×2.6+2.6×1.72
=（8.28+1.72）×2.6
=10×2.6
=26

Answer 2

6.5-3.9=2.6
8.28x2.6+2.6x1.72=2.6x（8.28+1.72）
=2.6x10=26

Answer 3

8.28×（6.5-3.9）+2.6×1.72
=8.28×2.6+2.6×1.72
=2.6×（8.28+1.72）
=2.6×10
=26

Answer 4

8.28＊（6.5-3.9）+2.6＊1.72
=8.28＊2.6+2.6＊1.72
=2.6＊（8.28+1.72）
=2.6＊10
=26

Answer 5

8.28*（6.5-3.9）+2.6*1.72
=8.28*2.6+2.6*1.72
=2.6*（8.28+1.72）
=2.6*10
=26
