Question

Find the product of (4 x 10^6) and (2 x 10^6). Write the final answer in scientific notation.

A 8 x 10^6

B 8 x 10^12

C 8 x 100^12

D 8 x 10^36

Answer 1

B 8 × 10¹²

Explanation:

well, in a multiplication of multiplications we can freely move and combine the operands.

(4 × 10⁶) × (2 × 10⁶) = 4×2 × 10⁶×10⁶ = 8 × 10¹²

remember, when multiplying factors with the same base units, we keep the base unit and simply add the exponents as the resulting exponent.
