Find the value of expression atimes b+c when a=3,b=5,c=7 square 2 leqslant t = (a)/(b) sqrt ((a)/(b))(sqrt (a))/(sqrt (b)) sqrt (n) -sqrt (n) sqrt [n](m) a^b (sqrt (a))/(b)

The question asks to find the value of the expression given the values of , , and . Here, , , and . The expression involves two operations: multiplication and addition. According to the order of operations, we first perform the multiplication, and then the addition. So, we first calculate . Then, we add the value of to this result: . Therefore, the value of the expression when , , and is 22.
