Answer:
A=8,000,000
B=1,000,000
Step-by-step explanation:
A=8B
A+B=9,000,000
8B(because A=8B)+B=9,000,000
9B=9,000,000
B=1,000,000
A=8*B=8*1,000,000=8,000,000

You measure two quantities as A=1.0m±0.2m, B=2.0m±0.2m. We should report correct value for
AB
as
Medium
Solution

Correct option is
D
1.4m±0.2m
Here, A=1.0m±0.2m, B=2.0m±0.2m
AB=(1.0m)(2.0m)=2.0m

AB
=
2.0m
=1.414m
Rounding off to two significant figures, we get
AB
=1.4m
