Answer:
radical expression
Step-by-step explanation:
U have to subtract the 2 numbers.
The bigger number is 1,787 * 10^9
the smaller is 8,867*10^8
Now convert the bigger to the same power of 10
1,787 * 10^9 = 17,87 * 10^8
17,87 * 10^8 - 8,867*10^8 = 9,003 * 10^8
I believe that 21 is d 27 over 17
I believe that 22 is d because 16 divided by 3.20 is 5
sorry if I am wrong
I hope this helps you
