\(1.002^4 = (1+2*10^-^3)^4=(1+4*10^-^6+4*10^-^3)^2=(1+0.000004+0.004)(1+0.000004+0.004)\) get rid of 0.000004
\((1+0.004)(1+0.004)=1+0.004+0.004+0.004*0.004\) get rid of 0.004*0.004
and your result is
\(1+0.004+0.004=1.008\)

As compared to 1, 0.002 is a very small quantity. Thus, we can write (1+0.002)^4 is nearly equal to (1+4*0.002) = 1.008.As the question asks for approximation to three decimal places, the further terms will anyways not come into picture.
