Question

4.7x4.7+4.7x3.2+4.7x11+4.7，简便运算怎么算？

Answer 1

4.7x4.7+4.7x3.2+4.7x11+4.7
=4.7x(4.7+3.2+11+1)
=4.7x19.9
=4.7x(20-0.1)
=4.7x20-4.7x0.1
=94-0.47
=93.53
望采纳，谢谢

Answer 2

4.7×4.7+4.7×3.2+4.7×11+4.7
=4.7×（4.7+3.2+11+1）
=4.7×19.9
=93.53

Answer 3

都有4.7就先提取4.7，再做括号内的加法。
4.7*4.7+4.7*3.2+4.7*11+4.7
=4.7*（4.7+3.2+11+1）
=4.7*（8.9+11+1）
=4.7*（10.9+10)
=4.7*（10+10+1-0.1）
=47+47+4.7-0.47
=94+4.23
=98.23

Answer 4

4.7 × 4.7 + 4.7 × 3.2 + 4.7 × 11 + 4.7
= 4.7 × (4.7 + 3.2 + 11 + 1 + 0.1) - 0.47
= 4.7 × 20 - 0.47
= 94 - 0.47
= 93.53
