Find z_(1)z_(2). Write the answer in standard form. {:[z_(1)=7cis ((pi)/(3))],[z_(2)=2cis ((11 pi)/(6))]:}

Determine total tape needed: Determine the total amount of electrical tape needed and the amount of tape on each roll. The electrician needs 8,000 centimeters of electrical tape, and each roll contains 2,000 centimeters of tape.Calculate rolls needed: Calculate the number of rolls needed by dividing the total amount of tape by the amount of tape on each roll. Number of rolls needed = Total amount of tape needed ÷ Amount of tape in each roll Number of rolls needed = 8,000 cm ÷ 2,000 cm/rollPerform division for rolls: Perform the division to find the number of rolls. Number of rolls needed = 8,000 cm ÷ 2,000 cm/roll = 4 rolls

Determine total tape needed: Determine the total amount of electrical tape needed and the amount of tape on each roll. $\newline$ The electrician needs $8,000$ centimeters of electrical tape, and each roll contains $2,000$ centimeters of tape.
Calculate rolls needed: Calculate the number of rolls needed by dividing the total amount of tape by the amount of tape on each roll. $\newline$ Number of rolls needed $=$ Total amount of tape needed $\div$ Amount of tape in each roll $\newline$ Number of rolls needed $= 8,000 \, \text{cm} \div 2,000 \, \text{cm/roll}$
Perform division for rolls: Perform the division to find the number of rolls. $\newline$ Number of rolls needed = $8,000 \, \text{cm} \div 2,000 \, \text{cm}/\text{roll} = 4 \, \text{rolls}$
