Worked solution

1. 对等号左边的算式利用乘法分配律进行变形

根据乘法分配律,可以将等号左边的算式 38×101−3838 \times 101 - 38 变形为:
38×101−38=38×101−38×1=38×(101−1)38 \times 101 - 38 = 38 \times 101 - 38 \times 1 = 38 \times (101 - 1)

2. 计算括号内的减法并与等式右边进行比较

计算括号内的减法:
38×(101−1)=38×10038 \times (101 - 1) = 38 \times 100
等号左边计算得出的结果与等号右边的式子 38×10038 \times 100 完全一致,因此原等式成立。
