Question

please give the correct answer!!​

Answer 1

Answer:

option C

Explanation:

according to binomial theorem, if x is very small number less than 1 then,

$(1+x)^{n} = 1+ nx$

use the same principle here.

ΔT << T

so, ΔT/ T is a number much less than 1.

So, you can apply the principle here considering ΔT/T as x in the formula.

Answer 2

Answer:

option C

Explanation:

according to binomial theorem , if x is very small number then , ( 1 + x ) " = 1+ nx use the same principle here
