Answer:

Step-by-step explanation:

To perform this multiplication I would rewrite the expression as

81*4*100. This is easier to do mentally: 4 times 81 is 324, and then 324 times 100 is 32,400. There are of course other approaches involving factoring the original expression and performing multiplication.
