Answer:

$2^{7}$

Step-by-step explanation:

when x=2, the expression is now:

$(2^{4})(2^{3} )$

First, multiply the terms with the same base by adding their exponents:

$2^{4+3}$

Add:

$2^{4+3} =2^{7}$

Hope this helps!! <3

Answer:

Yes, vector u and vector v are equivalent vectors.

Step-by-step explanation:

The value of a vector is the difference between its terminal point and its initial point:

u = P2 -P1 = (6-8, 5-3) = (-2, 2)

v = P4 -P3 = (9-11, 10-8) = (-2, 2)

Vectors u and v are both (-2, 2), so are equivalent vectors.

What is the factored form of 8x^24-27y^6

zalisa [80]

Factoring: $8x^{24}-27y^6$

Theory : A difference of two perfect cubes, $a^3-b^3$ can be factored into

$(a-b)*(a^2+ab+b^2)$

Proof : $(a-b)*(a^2+ab+b^2)=$

$a^3+a^2b+ab^2-ba^2-b^2a-b^3=$

$a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3=$

$a^3+0+0+b^3=$

$a^3+b^3$

Check : 8 is the cube of 2

Check : 27 is the cube of 3

Check : $x^{24}$ is the cube of $x^8$

Check : $y^6$ is the cube of $y^2$

Factorization is :

$(2x^8 - 3y^2)*(4x^{16} + 6x^8y^2 + 9y^4)$
