Question

ifx=7+4√3 find x+1/x​

Answer 1

Answer:

x=7−43–√

1x=17−43–√×7+43–√7+43–√=7+43–√72−48=7+43–√49−48=7+43–√

x+1x=7−43–√+7+43–√=7+7=14.

Answer 2

experiment explained below demonstrate how a liquid enclosed in a vessel exerts pressure in all directions.

Procedure:

Fill a larger plastic bottle or a can with water

Set it on a horizontal surface

Punch a few holes in the vessel at any point below the liquid surface Observation

Through each of the hole, water spurts out inference

The spurting out of liquid indicate that the liquid exerts pressure at every point on the walls of the can/bottle
