If 1/√a-√b=1/3 and 1/√a+√b=1/2, then find the difference of a and b.

ANSWER:

If and then the difference of a and b is 6

SOLUTION:

Given, → ----- (1)

And → --- (2)

We have to find difference of a and b.

Now, add (1) and (2)

Adding above two equations, we get,

substitute value in (2)

Now, difference of a and b is a – b =

Hence, the difference of a and b is 6.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

the answer is 40.
