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 !
