How do you rewrite an equation in exponential form ?

4=log(x)

For logarithmic equations,  logᵇ(x)=y  is equivalent to  b∧y=x  such that  x>0,b>0, and  b≠1.

In this case,  b=10,  x=x, and  y=4.

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.
