Answer 1

Answer:

It will be 2nd option

Explanation:

2.0m+0.2m

Answer 2

Answer:

$a = 2.0m \: \frac{ + }{} \: 0.1m \\ b = 2.0m \: \frac{ + }{} \: 0.1m \\ then \\ ab =( 2.0m \: \frac{ + }{} \: 0.1m) {}^{2} \\ because \: sign \: in \: a \: and \: b \: is \: same \\ so \: \: \\ (ab) {}^{ \frac{1}{2} } = (2.0m \: \frac{ + }{} \: 0.1m \: ) {}^{2 \times \frac{1}{2} } \\ = 2.0m \: \frac{ + }{} \: \: 0.1m$

correct answer is option (i)
