Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.

The green ribbon is 96 cm long and if 67 cm of the green ribbon is used to wrap a present, the amount left is 29 cm

An equation is an expression that shows the relationship between numbers or variables.

Let x represent the length of the green ribbon.

The green ribbon is 38 cm longer than the blue ribbon, hence:

x = 58 cm + 38 cm

x = 96 cm

The green ribbon is 96 cm long.

If 67 cm of the green ribbon to wrap a present, the amount left is:

Amount left = 96 cm - 67 cm = 29 cm
