Respuesta:
a. (32+15)-64*23÷(13)2
47-[tex]\frac{64*23}{13}[/tex]*2
= 47-[tex]\frac{1472}{13}[/tex]*2
= 47-[tex]\frac{2944}{13}[/tex]
= -[tex]\frac{2333}{13}[/tex]
b. (12)2-14*23+√916
24-322+2[tex]\sqrt{229}[/tex]
= -298+2[tex]\sqrt{229}[/tex]
c. 64÷(23-12+34)*(13)2
64÷45*13*2
= [tex]\frac{64}{45}[/tex]*13*2
= [tex]\frac{1664}{45}[/tex]
