Answer:
We have to choose any one from option B and option C
Step-by-step explanation:
We have to perform a subtraction of two decimal numbers.
(9.43 - 4.286) = (9.430 - 4.286) = 5.144.
Hence, the answer is 5.144 which is given both options B and C.
In case there are two options with the same value and the value is the answer, then you choose any one of them but not both.
Here in our case, we have to choose any one from option B and option C and we will be rewarded full marks. (Answer)

Remember, to solve this, you multiply the bigger numbers and add the exponents. if the exponents are negative they go on the bottom and are switched to a positive, you are trying to make the problem positive.
number 15 is A because you multiply 2 and 4 to get 8 and you add the exponents together if they are positive and are not a fraction
number 16 is D because you multiply all the bigger numbers together to get 48, then you add all the b's together to get four and all the a's to get 8
number 17 is D because you do the same by multiplying 5 and 3 to get 15, then adding the exponents to get 3 x's and 6 y's
number 18 is D because you multiply 5 and 2 and add the exponents to get 3 x's and 5 y's because the x without a number is a one so you make that one count and add 2 and one together to get 3
number 19 is B because the smaller number is negative so the y goes to the bottom and it becomes a y^3
number 20 is A because both exponents are negative and go to the bottom and become positive
number 21 is D because its the same case as number 20
Lastly Number 22 is B
