Answer 2

I can help you with math problems and other topics. To solve the expression x+(x-y)*3-ya*b+c*(a-b)2b+m*n:7, we need to apply the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. Here are the steps:

- First, we simplify the terms inside the parentheses by applying the distributive property: c*(a-b) = c*a-c*b. - Next, we evaluate the exponents: (a-b)^2 = (a-b)*(a-b) = a^2-2ab+b^2. - Then, we perform the multiplication and division from left to right: (x-y)*3 = 3x-3y, -ya*b = -aby, c*a-c*b = ac-bc, 2b*m*n = 2bmn, m*n:7 = mn/7. - Finally, we do the addition and subtraction from left to right: x+3x-3y-aby+ac-bc+a^2-2ab+b^2+2bmn+mn/7 = 4x-3y-aby+ac-bc+a^2-2ab+b^2+2bmn+mn/7.

The final answer is 4x-3y-aby+ac-bc+a^2-2ab+b^2+2bmn+mn/7. You can check your answer using an online calculator or a math solver.
