Multiply. (4 * 10^4)(2 * 10^4) Choices: (A)8 * 10^8 (B)8 * 10^9 (C)8 * 10^0 (D)6 * 10^8

Group Terms: We have the expression (4 * 10^4)(2 * 10^4). First, we need to group the coefficients (4 and 2) and the power terms (10^4 and 10^4) together.Multiply Coefficients: Multiply the coefficients. What is 4 × 2? Calculation: 4 × 2 = 8Combine Power Terms: Combine the power terms 10^4 × 10^4. When multiplying powers with the same base, we add the exponents. Calculation: 10^4 × 10^4 = 10^(4 + 4) = 10^8Final Scientific Notation: We found: Coefficient = 8 Power term = 10^8 Now, write the final answer in scientific notation by combining the coefficient and the power term. Scientific notation: 8 × 10^8
