The part of the question that says " x 10⁶ " means
" move the decimal point 6 places that way ===> ".
So take the 1.986 and do that to it.
If there aren't enough places to move the decimal point far enough,
add some zeros to the 1.986 before you move the point.

Answer:
The waves interfere destructively occur. The further explanation is given below.
Explanation:
The transmissions almost commute with either the speed of light. So, use the following relation to calculate the wavelength of that same TV signal.
⇒ λ = ![\frac{c}{v}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7Bv%7D)
⇒ = ![\frac{3\times 10^{8}m/s }{75 \ MHz(\frac{10^{6}Hz}{1 \ MHz})}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Ctimes%2010%5E%7B8%7Dm%2Fs%20%7D%7B75%20%5C%20MHz%28%5Cfrac%7B10%5E%7B6%7DHz%7D%7B1%20%5C%20MHz%7D%29%7D)
⇒ = ![4 \ m](https://tex.z-dn.net/?f=4%20%20%5C%20m)
The variance in the route between both the 2 waves that approach the recipient is 248 m, also because wave passes 124 m two times. And then after the plane's reflective thinking the waves iteration adjustments by half.
⇒ Δ
=
λ
If the value of the above expression is a positive integer, the waves interfere constructively, as well as the waves disrupt destructively if they are integral multiples of the half. Caused by a change of step due to the reflection the component of half would be added.
⇒ ![248 \ m=(m+\frac{1}{2})(4 \ m)](https://tex.z-dn.net/?f=248%20%5C%20m%3D%28m%2B%5Cfrac%7B1%7D%7B2%7D%29%284%20%5C%20m%29)
⇒ ![m = 61.5](https://tex.z-dn.net/?f=m%20%3D%2061.5)
Since the value of m seems to be an integral multiple of the half.
Therefore, the waves interfere destructively
