Q. evaluate

8-\frac{m}{n}+p^2

when

m=8

,

n=2

,

p=7

Substitute given values: First, we need to substitute the given values into the expression. So we replace $m$ with $8$ , $n$ with $2$ , and $p$ with $7$ in the expression $8 - \frac{m}{n} + p^2$ . $\newline$ Calculation: $8 - \frac{8}{2} + 7^2$
Perform division: Next, we perform the division in the expression. We divide $8$ by $2$ . $\newline$ Calculation: $8 - 4 + 7^2$
Calculate square of p: Now, we calculate the square of $p$ , which is $7^2$ . $\newline$ Calculation: $7^2 = 49$
Add division and square: We then add the results of the division and the square to the remaining part of the expression. $\newline$ Calculation: $8 - 4 + 49$
Perform addition and subtraction: Finally, we perform the addition and subtraction in the expression from left to right. $\newline$ Calculation: $8 - 4 + 49 = 4 + 49 = 53$
