Quizplus · Accepted Answer

When multiplying numbers in scientific notation, you multiply the coefficients (3.2 * 4.4 = 14.08) and add the exponents (6 + 2 = 8). To keep it in proper scientific notation, adjust 14.08 to 1.408 and increase the exponent by 1, resulting in $1.408 \times 10^9$.

Perform the Operation (3.2×106)(4.4×102)\left( 3.2 \times 10 ^ { 6 } \right) \left( 4.4 \times 10 ^ { 2 } \right)(3.2×106)(4.4×102)

Perform the Operation $\left( 3.2 \times 10 ^ { 6 } \right) \left( 4.4 \times 10 ^ { 2 } \right)$
