a=b+2
b+2=a
b-a=-2
Therefore,(b-a)^4=-2*-2*-2*-2=16

b - a = -2
-2^4 = 16

a=b + 2
a - b=2

then you invert the values by mutipling by -1 which will make:

-a + b= -2

and if you are really anal or it's confusing -a + b is the same as b - a.

so b - a = -2

-2 to the power of 4 is like saying -2 x -2 x -2 x -2

-2 x -2=4
4x -2= -8
-8 x -2=16

Because negative times a negative is always a positive, and a negative times a positive is always a negative.

So your answer is 16

Hope this helps and that you learned something.

a = b + 2

(b - a) = (b - (b + 2))
You substitute b + 2 for a

= (b - b - 2)
Distribute the minus sign

= -2
b - b = 0

(b - a) ^ 4

-2 ^ 4 = 16
Substitute (b - a) for -2 and raise -2 to the 4th.

b-a=-2
(-2)^4=16

I think that is should be like this:

a = b + 2

(b-a) to the power of 4 is?
____________________________________________________
Since a is equal to b +2, then sub b + 2 into (b-a) to the power of 4.

{b-(b+2)} to the power of 4

Expand the bracket -(b+2) = -b-2

(b-b-2)

b - b = 0 so left -2 to the power of 4

Therefore (-2) to the power of 4 equals to 14

a = b + 2
b - a = -2
(b - a)^4 = (-2)^4 = ?

2006-11-09 17:45:37 · answer #7 · answered by Helmut 7 · 0 0

the answer is 16 cuz:

if a=b+2, then (b - a)^4 is...

(b-[b+2])^4

(b - b + 2)^4

(2)^4

16

yay!!!... hot women come dance and sing with me!
