Question

A newborn baby has 26,000,000,000 cells. An adult has about 1.9×10³ times as many as a newborn. About how many cells does an adult have? write your answer in scientific notation.
p.s please do not use the ^ thingies, I don't get them

Answer 1

*Hint* the ^ just means that the following numbers are powers like 1.9x10^3 is same as 1.9x10³


To figure this out just multiply 

26000000000 × 1.9x10³ = 4.94x10¹³ cells in adults
