The first wrestler weighed more at the beginning of the diet.The second wrestler gains weight more quickly.

Step-by-step explanation:

For the first wrestler, we can see that from month to 4.5 , the wrestler's weight gets to be from kilograms to 101.75 kilograms. This means that the diet made the wrestler gain $\red{6.75}$ kilograms of weight every $\red{1.5}$ month. We can also see that it's consistent with from month 4.5 to .

For the second wrestler, we can see on the graph that the diet makes the wrestler gain weight in linear fashion. This means that their weight gain is consistent. Let's find how much the wrestler is gaining weight for every 1.5 months. At the moment when the wrestler started to diet, their weight is $\red{75}$ kilograms. At month 1.5 , we can see that the wrestler's weight is 82.5 . Now we can see that the wrestler gains $\blue{7.5}$ kilograms of weight every $\blue{1.5}$ months.

The first wrestler gains $\red{6.75}$ kilograms of weight every $\red{1.5}$ month while the second wrestler gains $\blue{7.5}$ kilograms of weight every 1.5 months. The second wrestler gains weight more quickly.

The second wrestler weighed $\blue{75}$ at the beginning of the diet. We are not provided of weight of the first wrestler when they started dieting but we do know that they gain $\red{6.75}$ kilograms of weight every 1.5 months. The first wrestler must weigh twice of $\red{6.75}$ kilograms of kilograms because month is twice 1.5 months.

$\red{90 -6.75 \cdot 2} \\ \red{90 -13.5} \\ \red{76.5}$

The first wrestler weighed more at the beginning of the diet.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: $\sqrt{\frac{ {72x}^{16} }{ {50x}^{{{36} }}}} = \frac{ { \sqrt{72}x}^{ {16}^{ (\frac{1}{2}) } } }{ { \sqrt{50} x}^ {{36}^{ (\frac{1}{2}) } }}$ multiply exponents per exponent rules to get: $\frac{ { \sqrt{72}x}^{8} }{ { \sqrt{50}x}^{18} }$ remember you subtract exponents from the denominator and add exponents in the numerator so: $\sqrt{ \frac{72}{ 50}} \times ( {x}^{(8 - 18) } ) = \sqrt{ \frac{36}{25} } \times ( {x}^{ - 10} )$ simplify further: $\frac{6}{5} {x}^{ - 10} = \frac{6}{5 {x}^{10} }$ so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
