<span>difference of squares formula:
</span>a^2<span> – b^</span>2<span> = (a + b)(a – b)
</span>so answers are
<span>(3 + xz)(–3 + xz)
</span><span>(y2 – xy)(y2 + xy)
</span><span>(64y2 + x2)(–x2 + 64y2)
</span><span>
cause
</span><span>(3 + xz)(–3 + xz)
= </span><span>(xz + 3 )(xz - 3)
= x^2z^2 - 9
--------------
</span>(y^2 – xy)(y^2 + xy)
= y^4 -x^2y^2
----------
<span>(64y^2 + x^2)(–x2 + 64y^2)
=</span>(64y^2 + x2)(64 - x^2)<span>
= 64^2 y^4 - x^4</span>
Step-by-step explanation:
3(4 *to the power of 2* - 3*to the power of 2*)
24-23 x 3
3*to the power of 3* - 3*to the power of 2
(6*to the power of 2* - 3) (9*to the power of 2* - 70)
- (6²-3)(9²-70)
- (36-3)(81-70)
- (33)(11)
- 363
Hence, Option d. is the correct answer because it gives answer 3 when it is solved.
Translate it
remember that

translates to

so we can say it equals y
so

translates to

we want to find the values of x that make it undefined
well, we know that

must be greater than 0
so we do
it is defined for
x-4>0
add 4
x>4
it is defined for all values such that x>4
