Carbon dating is an effective way to measure the age of organic materials. By measuring the presence of the C4 isotope, a suitable estimate can be found for
14
how old/authentic an artifact is. A fossil dug up at an archaeological site is
examined and it is found that its mass in C? has decayed by 99.7% to 0.800g.
What was its original mass?

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
