We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h

No, becasue of PEMDAS
so parenthasees first
exponents next
mulitplciation next
(-2)^4=-2 times -2 times -2 times -2=positive number since even number of negative signs
-2^4=-1 times 2^2=-1 times 2 times 2 times 2 times 2=negative number since odd number of negative signs
