Answer:
560x^3
Step-by-step explanation:
The formula is
(r + 1)th term of (a + x)^n = nCr a^(n-r)x^r
So 5th term = (4 + 1)th term
= 7C4 x^(7-4) (-2)^4
= 35x^3*16
= 560x^3

Answer:
No the two expressions are not equivalent.
Step-by-step explanation:
the given two expressions t=5 and t=9 are not equivalent because t being a variable cant take two numbers at a same time.however if they are placed in given two expressions of 't' such that that they give equal value when the first expression gives a value 'a' at t=5 while the other expression gives a value 'a' at t=9 then those two expressions will be equal.
