Compute the following with regard to significant figures (i) 4.6xx0.128 (ii) `(0.9995xx1.53)/(1.592)`

Explanation

Here (i) `4.6 xx0.128 = 0.5888 = 0.59`
The result has been rounded off to have two significant digits (as in 4.6)
(ii) `(0.9995xx1.53)/(1.592) = 0.96057 = 0.961`
The result has been rounded off to three significant digits (as in 1.53)
