3.4^9 is the answer/.............
Answer:
18.05 g
Step-by-step explanation:
The multiplier of the initial quantity is ...
(1/2)^(t/1690)
so, for t=250, this becomes ...
(1/2)^(250/1690) ≈ 0.902545
Then the quantity remaining of the initial 20 g is ...
(20 g)(0.902545) ≈ 18.05 g
Because every number with the decimal point have a zero infinit so it's not matter they're are same
I actually think its b cause it can't be d (thats obvious) yh........but i might be wrong
