Answer:
Step-by-step explanation:
There are 47 acres and the farmer is planting 140,000 per acre.
You got to times 140,000 by 47 but you can multiply 14 by 47 instead and place the zero later.
So take 10 times 47 and that is 470
Then take 4 times 47 and that is 188
Add 470 and 188 and you get 658
Take 658 a place the four zeros and you get 6,580,000 seed

Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.
