Answer:
by 12 cause 6×12 is 72 so if you multiply the whole thing by 12 it would be equal to 24/72
A: x= 6+3 squareroot 10 ... Its letter A
<h3>
Answer: E) x^5</h3>

=====================================================
Explanation:
We simply take half of the exponent 10 to get 5. This applies to square roots only.
So the rule is 
A more general rule is
![\sqrt[n]{a^b} = a^{b/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5Eb%7D%20%3D%20a%5E%7Bb%2Fn%7D)
If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.
Answer:
Decay
since 0.292 is less than 1
% rate of decrease
1 - 0.292 = 0.708
70.8%
1/4 of 4/5
=16/20 divided by 5/20
=16/20*20/5
=320/100
=3.2 or 3 1/5
