Answer:
21. 13,338,640,000
22.11500
Step-by-step explanation:
21: So first you would start in the parenthesis 10 to the power of 6 which equals 1,000,000 and the you would multiply 8.64*1,000,000 = 8640000 then you would move the the next parenthesis and you would do 10 to the power of 10 which equals 10,000,000,000 then you would times the by 1.334 = 13,340,000,000 and the you would add 8640000+13,340,000,000 and you would get 13, 338,640,000
22. First do 10 to the power of five and then get 100,000 then times by 1.21 and that equals 121000-9500 and get 11500
