2^4n × 2^ 2n = 512<br> What is the value of n.

Marina86 [1]

Step-by-step explanation:

${2}^{4n} \times {2}^{2n} = 512$

${2}^{4n} \times {2}^{2n} = {2}^{9}$

${2}^{4n + 2n} = {2}^{9}$

$6n = 9$

$n = \frac{3}{2}$

what algebraic expression must be added to the sum of 3x squared + 4x + 8 and 2x squared -6x + 3 to give 9x squared -2x - 5 as t

gregori [183]

<span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 to give result as 9x^2 -2x - 5

</span>3x^2 + 4x + 8 + 2x^2 - 6x + 3
= 5x^2 - 2x + 11

so

9x^2 -2x - 5 - (5x^2 - 2x + 11)
= 9x^2 -2x - 5 - 5x^2 + 2x - 11
= 4x^2 -16

answer

expression (4x^2 -16) must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)
