Explain why it would not make sense to approximate 256 using the binomial theorem for the binomial (20 + 5)6.

Olenka [21]

The formula for the Binomial Theorem with a power 6 is as:

$(x+y)^6=x^6+6x^5y+15x^4y^2+20x^3y^3+15x^2y^4+6xy^5+y^6$

Thus, if we plug in 20 for x and 5 for y, our first term itself will be $20^6=64000000$ which is much greater than 256 and thus it will not make any sense to use $(20+5)^6$ to approximate 256 using the binomial theorem.

Also, it will not make any sense to use $(20+5)6$ as that has no power and we know that Binomial Theorem makes use of Power. Anyway, $(20+5)6=150\neq 256$ .
