The coefficients of the first four terms in the expansion of (a + b)^5 are a) 1, 3, 5, 7 b) 1, 4, 6, 4 c) 1, 2, 3, 4, 5 d) 1, 5, 10, 10

the answer is D

Step-by-step explanation:

when expanded (a+b)^5 is a^5+5a^4 b+10a^3 b^2+10a^2 b^3+5ab^4+b^5

and as you can see the answer is 1 5 10 10 these are the first four coefficients
