Step-by-step explanation:

Answer 2

Given:

7,5 =101

6,2 =24

3,8 = 28

To find:

5,4 =?

Solution:

In the given question second equation is wrong if this equation value is 20 then the solution can be defined as follows:  

Apply formula:

$(A, B) = A\times B\times(3+0)-4\\\ Then,\\(C, D) = C\times D\times(3+0-2)+4\\\ then \ the \ series\ would \ be\\(E , F) = E\times F\times (3+1)-4\\\ so \ next \ format \ is\\(G, H) = G\times H\times(3+1-2) +4$

Solve:

$(7, 5) = 7\times 5\times (3+0) - 4 = 101\\ (6, 2) = 6 \times2 \times (3+1-2) -4 = 20 \\ (3, 8) = 3 \times 8\times (3+0-2)+4= 28\\(5, 4) = 5 \times 4 \times (3+1) -4 = 76$

The final answer is "76".
