Multiply by 122. Thats your answer. Hope this helps
Answer:
x=27
Step-by-step explanation:
To evaluate the expression: ![[(3^{-5})(3^4)]^3](https://tex.z-dn.net/?f=%5B%283%5E%7B-5%7D%29%283%5E4%29%5D%5E3)
Step 1: Innermost group, apply the product of powers (
Therefore:
We then have:
![=[3^{-1}]^3](https://tex.z-dn.net/?f=%3D%5B3%5E%7B-1%7D%5D%5E3)
Step 2: Apply the power of a power
![[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}](https://tex.z-dn.net/?f=%5B3%5E%7B-1%7D%5D%5E3%3D3%5E%7B-1%20%5Ctimes%203%7D%20%3D3%20%5E%7B-3%7D)
Step 3: Apply the negative exponent
Step 4: Simplify
Therefore, the value of x in the simplified expression is 27.
Answer: 571
To get this answer, we first need to compute the value of f(4). This happens when we plug x = 4 into f(x)
f(x) = 5x + 4
f(4) = 5*4+4 ... each x replaced with 4
f(4) = 20+4
f(4) = 24
Now replace every 'x' in g(x) with f(4) like so
g(x) = x^2 - 5
g(x) = ( x )^2 - 5
g(f(4)) = ( f(4) )^2 - 5 .... every x replaced with f(4)
g(f(4)) = ( 24 )^2 - 5 ... see note below
g(f(4)) = 576 - 5
g(f(4)) = 571
note: the f(4) on the right hand side of that equation is replaced with 24, because we found earlier that f(4) = 24. In other words, f(4) is the same as 24.
