For this case we must find an expression equivalent to:
Then, we take common factor 8:

By definition of power properties we have to:

So:

Since both terms are perfect cubes, we factor using the cube difference formula:

Where:

So:
Answer:

Hat grade are u? I'm just asking cause the formulas are going with grade I could help if u want me too
Answer:
1 = (sin^2 A + cos^2 A)^2 = sin^4 A + cos^4 A + 2 sin^2 A cos^2 A
so
sin^4 A + cos^4 A
= 1 - 1/2 sin^2 2A
= 1 - 1/4 (1- cos 4A)
= 1/4 (3+cos 4A)
Step-by-step explanation:
