Anewborn baby has about 26,000,000,000 cells. an adult has about 4.94 x 13 cells. how many times as many cells does an adult have than a newborn? write your answer in scientific notation.

Well after pressing the link i realized you meant 4.94 x 10^13. But anyways this is easy:)
all we have to do is move the decimal to the right 13 times and so lets do that
first just write a whole bunch of zeros
4.940000000000000000
soo here we go and lets move it 13 times to the right
49400000000000.0
                          -^
see where the decimal is now?
now we just subtract that number from 26,000,000,000
so lets do that:)
49,400,000,000,000 - 26,000,000,000 = 49,374,000,000,000
now thats our answer! but it says to put our answer is scientific notation so lets do that
all we have to do is put a decimal right after the last zero and count as we move it all the way in between the 4 and 9 
49,374,000,000,000
4.9374000000000 see where the decimal is now? good because we moved it 13 times 
so we write
4.9374 x 10^13  and this ^13 means to the 13th power:)
hope this wasnt confusing:)
and if it did help you then 
MARK ME BRAINLIEST! :D
