Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's solve
3(x-5)=18
Open the bracket
3x-15=18
Add 15 to both sides
3x=3
Make x the subject of formula by dividing both sides by 3
x=1
So the final answer is 1
Answer:
x = 114
Step-by-step explanation:

Use the formula: (a+b)(a-b) = a^2 - b^2
![x^4 - [(x^2)^2 - 1^2]\\\\x^4 - (x^4-1)\\\\x^4 - x^4 + 1\\\\\boxed{\bf{1}}](https://tex.z-dn.net/?f=x%5E4%20-%20%5B%28x%5E2%29%5E2%20-%201%5E2%5D%5C%5C%5C%5Cx%5E4%20-%20%28x%5E4-1%29%5C%5C%5C%5Cx%5E4%20-%20x%5E4%20%2B%201%5C%5C%5C%5C%5Cboxed%7B%5Cbf%7B1%7D%7D)
No matter what the value of 'x' is, the final answer will always be
1.
