Question

A term in the expansion of (2x-b)^11 is -92,400,000x^6. What is b?

Answer 1

do you know how to write the general term of any binomial expansion? :)

Answer 2

I don't think I do

Answer 3

okay its done like this-
suppose you have \(\large (a+b)^m\)

then the \((n+1)^{th}\) term is given by this expression-

\(\huge T_{n+1}=~^mC_r(a)^{m-r}(b)^r\)

here \(T_{n+1}\)-->\((n+1)^{th}\) term

Answer 4

now we have this-> \(\large (2x-b)^{11}\)
compare it with-> \(\large(a+b)^m\)

and find out the corresponding values of \(a\),\(b\) and \(m\)

Answer 5

Write the ratio in three different formats: a to b,a :b and a/b



The team spent 20 minutes on passing drills and 40 minutes on shooting drills.



Write the ratio of time spent on shooting drills to time spent on passing drills.
