Question:  

Use the generalized binomial expansion to expand (1 + x)^a up to the a = 5 and hence  determine (1.05)^5. to 5 decimal places.

Using the binomial theorem

Step-by-step explanation:

The binomial theorem is given by

For the given case, we have

So,

Therefore, using the binomial theorem

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
