Which expression is equivalent to assume

Option 2 is correct.

expression is equivalent to

Explanation:

Given the expression :

Radical form refers to a form of an algebraic expression in which we have a number or an expression underneath a radical.

Any algebraic expression involving exponents then, we can write it in radical form based on the fact that  is equivalent to the nth root of  i.e,

 =

then, we can write the given expression as:

= =

or                

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.
