Q. Multiply. Write your answer in scientific notation.(2×102)(4×105)______
Group Coefficients and Powers: We have the expression 2×1024×105. First, we need to group the coefficients and the power terms together.Coefficients: 2 and 4Power terms: 102 and 105
Multiply Coefficients: Multiply the coefficients together. What is 2×4?Calculation: 2×4=8
Combine Power Terms: Combine the power terms 102×105 into a single power of 10. When multiplying powers with the same base, we add the exponents.Calculation: 102×105=102+5=107
Write in Scientific Notation: We have found the coefficient to be 8 and the power term to be 107. Now, we write the final answer in scientific notation by substituting 8 for the coefficient a and 7 for the exponent b in the form a×10b.Scientific notation: 8×107
