Please answer!!! Will mark brainliest answer !!!
kenny6666 [7]

Answer:

A, D

Step-by-step explanation:

When we multiply the fractions, we can get:

\frac{1}{5^{4} }

This is also equivalent to:

5^{-4}

When looking at the answer choices, the only ones that equal 5^{-4} are A and D because:

(5^{-2})^{2}  =5^{-4}

5^{2}*5^{-6} = 5^{-4}

A chemist begins studying a radioactive sample that has a mass of 450 grams.
77julia77 [94]

Answer:

The question should say..... How much of the sample is left in......FIVE.....weeks? At least that is what I think you want to know.

The answer is 318.13 grams.

Step-by-step explanation:

450 - 6.7% = 419.85 grams ---- End of week 1

419.85 - 6.7% = 391.72 grams ---- End of week 2

391.72 - 6.7% = 365.47 grams ---- End of week 3

365.47 - 6.7% = 340.98 grams ---- End of week 4

340.98 - 6.7% = 318.13 grams ------ End of week 5
