.
Let us consider H(t).
The domain of this monster is defined by the condition that the expression under the logarithm is positive.
The denominator under the cubic root is always positive. So, the ratio under the cubic root is positive if and only if
the numerator is positive.
It, in turn, is determined by the term (6x - 10), because the factor is always positive.
Thus the domain of H(t) is 6x - 10 >= 0, or x >= = .
Similar analysis works for L(t).
Its domain is 4-3x > 0, or x < .
