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 $a \times b + c$ given the values of $a$, $b$, and $c$. Here, $a = 3$, $b = 5$, and $c = 7$. The expression $a \times b + c$ 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 $a \times b = 3 \times 5 = 15$. Then, we add the value of $c$ to this result: $15 + 7 = 22$. Therefore, the value of the expression $a \times b + c$ when $a = 3$, $b = 5$, and $c = 7$ is 22.
