To find the product, multiply the coefficients (9 and 2.2) and add the exponents of 10 ($6$ and $-1$). This gives $9 \times 2.2 = 19.8$ and $6 + (-1) = 5$, but to express in scientific notation, we adjust $19.8 \times 10^5$ to $1.98 \times 10^6$, moving the decimal one place to the right and increasing the exponent by 1.

Express the Value in Scientific Notation (9×106)(2.2×10−1)\left( 9 \times 10 ^ { 6 } \right) \left( 2.2 \times 10 ^ { - 1 } \right)(9×106)(2.2×10−1)
