Answer:
163,259,561,310
Step-by-step explanation:
To make this easier, first multiply the first two numbers:
2,357x8,870
I can take this apart using place values to make this easier:
2,000x8,000=16000000
300x800=240000
50x70=3500
7x0=0
Then add all these values together:
16000000+240000+3500+0=20906590
Then multiply that value by the remaining value to get your answer:
20906590x7809=163259561310
