Answer:
all i know is that number #2 is A
adding it all up is hard to figure out but #2 will show you that lay out so it mite be easier but i need help on this as well
Step-by-step explanation:
since there is always a decimal at the end of every value so :
= 262144.0
you move the decimal backwards if there is no decimal between the value. you place the decimal after the 1st digit, you will also count the digits you have passed :
= 2.62144 X 10^5
you passed 5 values so you put 5 in exponent form.
