\(\left(\dfrac{3}{6}\right)^2 + 7\times 4 - 5\\ = \left(\dfrac{1}{2}\right)^2 + 28 - 5\\ = \dfrac{1}{4} + 23\\ = 23.25 \quad \text{ OR } \quad \dfrac{93}{4}\)

In this problem you indicated to have (3/6) to the second power like you said + 7x4 - 5 

 

 

so first we multiply 3/6 x 3/6 we get 9/36 simplifying that we get 1/4 

 

so now we have 1/4 times 2 which is 2/4 and simplifing that is 1/2 and 7 x 4 = 28 

 

so 28 + 1/2 = 28 1/2 or in decimal forum ( see the pun there XD) is 28.5  

 

so 28 1/2 - 5 =  23 1/2  but if you need decimal form it's 23.5
