which shows the following expression after the negative exponents have been eliminated? a^ 3 b^ -2 ab^ -4 ,a =/0,b b=/0

(a ^ 3 * b ^ (- 4))/(a * b ^ (- 2))
ab^ 4 /a^ 3 b^ 2
- (a ^ 3 * b ^ 4)/(a * b ^ 2)
(a ^ 3 * b ^ 4)/(a * b ^ 2)

the answer is c hope it

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
