A car starts from rest and acquires a velocity of 72 km/h in 5s. Find the distance travelled by car assume motion of car is uniform.

Converting velocity into m/s

72x5/18=20 m/s²

Distance = Velocity *Time

20*5=100m

hope it's helpful

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
