Answer:
EH = 9.4
Step-by-step explanation:
A rhombus is a quadrilateral with equal length of sides.
Given that, EF = 13 and DF = 18
⇒ DH = HF =
= 9
The property that the diagonals of a rhombus are at right angle to each other.
Thus, applying the Pythagoras theorem, we have;
=
+
=
+
=
+
169 = + 81
= 169 - 81
= 88
EH =
= 9.381
The length EH is 9.4
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
