<u>Anna:</u>
1st month = 18 + = 18
inches
2nd month = 18 +
= 19
3rd month = 19 +
= 20
4th month = 20 +
= 21
5th month = 21 + = 21
<u>Grace:</u>
Because Anna is inches shorter than Grace, we can start the count from the third month:
1st month = 20
2nd month = 21
3rd month = 21
4th month = 21 +
= 22
5th month = 22 +
= 23
The root 
can be converted into the power 
. Therefore we can rewrite the problem as 
and then follow the exponent rules about a power to a power, multiplying 1/2 and 3/4 together.
Thus the problem becomes
, which then can be turned into ![\sqrt[8]{10} ^{3x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B10%7D%20%5E%7B3x%7D)
, making the last option our answer.
Thus the problem becomes
