Answer:
In above phara we come. To know that, the physical quantity is large by number of =x here state large than multiple which is =x*x*x
Nest phara the second is given that is =0.5
Of a length=4x because double is there
And mass increase by it should status.
Explanation:
X³*x+0.5+4x
=x⁴+4x+0.5
=if we put 0.5 in x value
=0.5⁴+4(0.5)+0.5
=0.0625+2+0.5
=2.5625
