The video tutorial explains how to evaluate an expression and express the result in scientific notation. It begins by dividing numbers to get an initial result, then applies the quotient of powers property to simplify the expression. Finally, it adjusts the result to fit scientific notation by moving the decimal point and modifying the power of 10.

What is the result of dividing 7 and 0.29 by 9?

• 0.71

• 0.61

• 0.91

• 0.81

What is the base used when applying the quotient of powers property?

• Base 8

• Base 10

• Base 2

• Base 5

What is the result of subtracting negative 6 from negative 9 in the context of powers of 10?

• 10 to the power of 3

• 10 to the power of -3

• 10 to the power of 15

• 10 to the power of -15

How do you adjust the power of 10 when moving the decimal point one place to the right?

• Keep the power the same

• Decrease the power by 1

• Increase the power by 1

• Double the power

What is the final expression in scientific notation after adjustment?

• 8.1 times 10 to the power of -3

• 8.1 times 10 to the power of -4

• 0.81 times 10 to the power of -4

• 0.81 times 10 to the power of -3
