sin^8 x - cos^8 x
= (sin^4 x + cos^4 x)(sin^4 x - cos^4 x)
= (sin^4 x + cos^4 x)(sin^2 x - cos^2x)(sin^2 x +cos^2 x)
=  (sin^4x + cos^4 x)( sin^2 x- cos^2 x)

Sorry I cant do 4 (d).

babymother [125]
If you want to know what is the number of m so first you can add 2 on both sides of equation like : 13 = 5m - 2 
                            +2        +2 ⇒ 13 + 2 = 5m ⇒ 15 = 5m ⇒ 15/5 = m ⇒ 3=m :))
i hope this be helpful

Answer:


Step-by-step explanation:

we have to find the dot product here.

From the formula of dot product of vectors,

we know-

if  X=<a,b,c>   and    Y=<d,e,f>

Then dot product of  X and Y is-

X.Y=ad+be+cf


Here, we get

v=<2 , -8 , -8>

and   w=<-2 , 6 , -5>

So, the dot product is-

v . w=2(-2)+(-8)(6)+(-8)(-5)

    =-4-48+40

    =-52+40

   =-12


So,  

v . w= -12
