Express the following calculations to the proper number of significant figures.
`((2.34xx10^(-8))(0.5))/(6.4)`

Text Solution

Verified by Experts

In this calculation 0.5 has minimum number of significant digits. It has only one significant digit. The result of this calculation is, therefore, to be rounded off to one significant digit.
`((2.34xx10^(-8))xx(0.5))/(6.4)= (1.17xx10^(-8))/(6.4) = 0.1828125 xx 10^(-8)` Here 8, after 1 is greater than 5, so the result after rounding off is `0.2 xx 10^(-8)`
