Final answer:

Scientific notation is used to express very large and very small numbers. In scientific notation, the coefficient is a number between 1 and 10, and the exponent is a power of 10. The given expression is not in scientific notation, but it can be converted by adjusting the coefficient and determining the exponent.

Step-by-step explanation:

Scientific notation is used to express very large and very small numbers as a product of two numbers. The first number, known as the coefficient, is a number between 1 and 10. The second number is always 10 raised to a certain power, known as the exponent. In the case of the expression 9.22 x 27, it is not in scientific notation because the coefficient, 9.22, is not between 1 and 10. To convert it to scientific notation, we can write it as 0.922 x 10, and because the decimal point was moved 2 places to the left, the exponent is -2.
