Question

find the simplified form of the expression. give your answer in scientific notation (3*10^8)(9*10^7)

Answer 1

first you want to multiply the non-exponential parts

3 * 9 = 27

then the non-exponential parts (10^8 * 10^9 = ?)

then, re-write them in scientific notation (the non-exponential part must be re-written as a number between 1 and 9.999 etc.)
