Answer:
i think its -1 box but im not sure
Step-by-step explanation:
Answer:

Step-by-step explanation:
You are going to integrate the following function:
(1)
furthermore, you know that:

lets call to this integral, the integral Io.
for a general form of I you have In:

furthermore you use the fact that:

by using this last expression in an iterative way you obtain the following:
(2)
with n=2s a even number
for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:

Answer:
x=1
Step-by-step explanation:
if it is truly 9^(x-1)=27^(x-1), then you dont really need to use the quadratic fromula.
I think you need to make it smaller amount like 2% is 5 so you can make it even more clearer.
