Express the following calculations to the proper number of significant figures. `((2.34xx10^(-8))(0.5))/(6.4)` |
|
Answer» 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)=0.1828125xx10^(-8)` Here 8, after 1 is greater than 5, so the result after rounding off is `0.2xx10^(-8)` . |
