The answer is either going to be the second one or the last one I'm going to go to with the last one if it's not the last one is the second one I hope I'm right if I'm not please let me know or if I am let me know
Answer:
63
Step-by-step explanation:
basta ayon sagot ko obob ko eh
C=P[(1+r)^n-1]
C = COMPOUND INTEREST
P = PRINCIPAL
r = rate per period
n = number of periods
In the binomial development, the main problem is calculation of binomial coefficients.
If we want to get term a∧8*b∧2 we see that this is the third member in binomial development (n 2) a∧n-2*b∧2
The given binomial is ((1/3)a∧2 - 3b)∧6, the first element is (1/3)a∧2, the second element is (-3b) and n=6 when we replace this in the formula we get
(6 2) * ((1/3)a∧2)∧(6-2) * (-3b)2 = (6*5)/2 * ((1/3)a∧2)∧4 *9b∧2= 15*(1/81)*9 *(a∧8b∧2) =
= 15*9* a∧8b∧2 = 135*a∧8b∧2
We finally get numerical coefficient 135
Good luck!!!
