Final answer:
The question involves multiplying expressions and converting them to scientific notation with appropriate significant figures. Rules for multiplication of exponentials include multiplying the digit terms and adding exponents for exponentials, cubing the digit, and tripling the exponent for cubes.
Step-by-step explanation:
The question asks for the multiplication of expressions and for the result to be in scientific notation with the correct numbers of significant figures and units. When dealing with expressions involving exponents and significant figures, it is important to follow the rules of multiplication and scientific notation. For example:
- For simple multiplication, just multiply the numbers while considering the appropriate number of significant figures.
- In scientific notation, when you multiply two exponentials, you multiply the digit terms normally and add the exponents of the exponential terms.
- When cubing exponential numbers, you cube the digit term and multiply the exponent by 3.
When working with positive and negative numbers, remember that multiplying two numbers of the same sign results in a positive number, whereas multiplying numbers with opposite signs results in a negative number.
