Answer:

Step-by-step explanation:

When a quantity is raised to a fractional power, you need to root it to the power of the denominator.

For example, (-64)^(1/2) = √(-64) 

Since you are taking the root of a negative, you will need to put an i (imaginary) in your answer.

six men completed a task in 24 hours and 48 minutes. how long would it take four men to complete the same task

Komok [63]

Answer:

37 hours and 12 minutes

Step-by-step explanation:

six men completed a task in 24 hours and 48 minutes which means (24 x 60) + 48 = 1488 minutes

x is the number of minutes it would take 4 men to complete

6(1488) = 4x

8928 = 4x

x = 2232

x = 2220 + 12 or 37 hours and 12 minutes
