The root of a product is equal to the product of the roots of each factor
24×h
Reduce the index of the radical and exponent with 2
4h
h4h−4=0
Cross multiply
4h−4=h×0
Simplify the equation
4h−4=0
Move the constant to the right-hand side and change its sign
4h=4
Divide both sides of the equation by 4
h=1
Raise both sides of the equation to the 2-th power to eliminate the isolated 2-th root
(h)2=12
Evaluate the power
h=1
Check if the solution is in the defined range
h=1,h>0
Solution
h=1
