Question

$a {2} + b {2} \div 3 \: \\ if \: a \: 7 \: \: b \: 4$
​

Answer 1

Answer:

21.67

Step-by-step explanation:

Given :

a =7 , b= 4

$a^{2} +b^{2} /3 = (7)^{2} +(4)^{2} /3$

                              = 49 + 16 / 3

                              = 65 /3

                              = 21.67

Answer 2

Answer:

$\frac {65}{3}$

Step-by-step explanation:

$\frac {a^2 + b^2}{3}$

$a=7,b=4$

$\frac {7^2 + 4^2}{3}$

$\frac {49 + 16}{3}$

$\frac {65}{3}$

$= 21.67$
