Answer:
0.010
Step-by-step explanation:
Given:
(x+y)^8
Applying binomial theorm to expand above expression, we get:
[tex]\sum _{i=0}^8\binom{8}{i}x^{\left(8-i\right)}y^i[/tex]
x^8+8x^7y+28x^6y^2+56x^5y^3+70x^4y^4+56x^3y^5+28x^2y^6+8xy^7+y^8
third term is 28x^6y^2
if x=0.3 and y=0.7 then
28x^6y^2= 28(0.3)^6(0.7)^2
=0.01000188 !
