Simplify 25-7[16+{5+(3÷3)-4×2}]​
Prove that
$\bf (cos \;x + cos \; y)^{2} + (sin \; x - sin \; y)^{2} = 4cos^{2}\dfrac{x +y}{2}(cosx+cosy)2+(sinx−siny)2=4cos22x+y​(cosx+cosy)2+(sinx−siny)2=4cos22x+y​(cosx+cosy)2+(sinx−siny)2=4cos22x+y​$

Answer 1

Answer:

I only know the first answer.

Step-by-step explanation:

25-7[16+{5+(3/3)-4x2}]

18{16+{5+1-8}]

18[16+{6-8}]

18[16+(-2)]

18(16-2)

18(14)

252

Hence,

     25-7[16+{5+(3/3)-4x2}]=252
