Answer:
Add 2 to each side
x=1/2
Step-by-step explanation:
(3√8x - 2 )= 4
Add 2 to each side
(3√8x - 2 +2= 4+2
3√8x = 6
Divide each side by 3
3/3√8x = 6/3
√8x = 2
Square each side
(√8x)^2 = 2^2
8x = 4
Divide each side by8
8x/8 = 4/8
x = 1/2

The amount of the radioactive substance is 374.6 g
<h3>How to determine the amount of
radioactive substance?</h3>
The given parameters are:
- Initial, a = 424 mg
- Rate, r = 6%
- Time, t = 2 hours
The amount of the radioactive substance is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 424 * (1 - 6%)^t
At 2 hours, we have:
A(2) = 424 * (1 - 6%)^2
Evaluate
A(2) = 374.6
Hence, the amount of the radioactive substance is 374.6 g
