Helloo:)
it’ll be loge (100) because ln = loge
(I’m not sure how to explain this, but I hope it helps:)!
Answer:
The equation that describes the amount of mass left after a time t of a radioactive isotope is the following:
where
is the mass of the sample at t = 0
is the half-life of the sample
For the element X in this problem,
We want to find the time t at which
So we need to re-arrange the equation making t the subject:
Step-by-step explanation:
Given:
The given expression is
To find:
The two other equivalent expressions.
Solution:
We have,
Using distributive property, we get
So, one equivalent expression is 
.
On further simplification, we get
Therefore, the second and fully simplified equivalent expression is 
.
Answer:
6
Step-by-step explanation:
Remember the Order of Operations:
Parentheses
Exponents
Multiplication/Division (whichever comes first)
Addition/Subtraction (whichever comes first)
In this case, we start by simplifying what is in the parentheses:
(16÷8)+(24÷6)
2+4
6
