Respuesta :

We will have the following:

*First expression:

[tex]9^2-7^2=20/(7-2)\Rightarrow32\ne4[/tex]

*Second expression:

[tex]48/8+2^3=5+3^2\Rightarrow14=14[/tex]

*Third expression:

[tex]\frac{8\cdot7}{2}-12=22-2\cdot3\Rightarrow16=16[/tex]

*Fourth expression:

[tex]\frac{150}{5^2}=30-4^2-12\Rightarrow6\ne2[/tex]
