How do you simplify scientific notations?

4.8 · 108

To solve this problem, one again must use PEMDAS first on the exponential term. Once this is done, one obtains (2 10)3 = 11 103(2 10)3 = 11 103. Then, multiplying the two single-digit numbers (8 and 6), one gets 48. Continuing with the solution, we now can multiply 103 with 104 to obtain 107 by adding the exponents (this can be done because each number has a common base, 10). We are now left with 48107. However, the last step is to write the answer in scientific notation, which is 4.8 108. Competency 013
