Mixed Format $$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$

Mixed format: $$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$ (with a space between the whole number and the numerator) Fraction format: $1 /4$
Reduce all fractions. The insulation to be used in a certain slot is as follows: fish paper, $h p=\frac{\sqrt{3}(E)(L)(E f f)(P F)}{746}$ inch; Tufflex, $1 /16$
inch; varnished cambric, $1 /32$
inch; and top stick, $1 / 8$ inch. What is the total thickness of all the insulation?
