Evaluate 10m +\dfrac {n^2}410m+ 4 n 2 10, m, plus, start fraction, n, squared, divided by, 4, end fraction when m=5m=5m, equal

Readme [11.4K]

Answer: $54$

Step-by-step explanation:

Given the following expresion provided in the exercise:

$10m+\frac{n^2}{4}$

You can follow these steps in order to evaluate it when $m=5$ and $n=4$ :

1. You need to substitute $m=5$ and $n=4$ into the given expression:

$10(5)+\frac{(4)^2}{4}$

2. Now you can solve the mutiplication:

$=50+\frac{(4)^2}{4}$

3. Since $4^2=4*4$ , you get:

$=50+\frac{16}{4}$

4. You must solve the division. Divide the numerator 16 by the denominator 4. Then:

$=50+4$

5. And finally, you must solve the addition. So, you get this result:

$=54$
