Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
The greatest common factor for 49 and 63 would be 7 since you can divide 7 into both numbers perfectly
Initial amount, .
Final amount, .
Time taken, t = 6:00 - 2:00 = 4 hour.
We know,
Therefore, the half-life of the isotope is 1.024 hours.
Hence, this is the required solution.
