To understand this question, we need some knowledge on radioactive decay. This type of nuclear decay is called a beta decay
<h3>Beta Decay</h3>This is the process where a radioactive material is fired or naturally emits a beta particle which is equivalent to the lose of an electron and spontaneously becomes an entirely different element.
The participating actors in this nuclear reaction are
- helium
- lithium
- electron
This is the decay process of helium particle in which it became a lithium particle and emitted an electron in the process.

Step-by-step explanation:
The question is not clear. However, I will treat the question as:
and:
Solving: and
Divide both sides by 26
Divide both sides by 50
Solving and
Express 1 as 2^0
Remove bracket
Cancel out 2
Divide both sides by 6
Express 1 as 5^0
Cancel out 5^0
Answer:
Only the equation is a function
Step-by-step explanation:
we have
Find out the inverse of f(x)
Let
y=f(x)
Exchange the variables (x for y and y for x)
Isolate the variable y
square root both sides
Let
The inverse function is not a function (because for one input value the function has two different output values)
therefore
Only the equation is a function
