Since we already have 3^7 you should know that 3 times 3 is 9. Here is how I would simplify it.
3^7 times 3^4 times 3^3
You should add all the exponents and get
3^14
27 is basically 3 times 3 times 3 which is why I chose to put 27 that way
f(x) = 6-5x
y = 6-5x .... replace f(x) with y
x = 6-5y .... swap x and y; solve for y
x+5y = 6
5y = 6-x
y = (6-x)/5
... replace y with the inverse function notation

I'm pretty sure there are no rational numbers between 9.6 and 9.7
Answer:
x=5
Step-by-step explanation:
3x^2=15x
Subtract 15x from both sides
3x^2-15x=0
Factor out 3x
3x(x-5)=0
Since 0 divided by any number is zero, we get that:
x-5=0
x=5
