Solve the following and express the result to appropriate number of significant figures : (i) `(2.51xx10^(-4)xx1.81xx10^7)/(0.4463)`
(ii) 1.567 + 0.958 - 0.27

Text Solution

Verified by Experts

The correct Answer is:
`(i) 10.2 xx10^3 (ii) 2.26`
(i) `(2.51xx10^(-4)xx1.81xx10^7)/(0.4463) = 10.1795xx10^3`
`=10.2xx10^3`,
rounded off to three significant digits.
(ii) 1.567 + 0.958 - 0.27 = 2.255 =2.26,
rounded off to two places of decimal.
