(2^8*5^-5*19^0)^-2x(5^-2/2^3)^4 x 2^28

Free_Kalibri [48]

Answer:

25 x^2

Step-by-step explanation:

Simplify the following:

((5^(-2)/2^3)^4 2^28 x x)/((2^8/5^5×19^0)^2)

2^28 = (2^14)^2 = ((2^7)^2)^2 = ((2×2^6)^2)^2 = ((2 (2^3)^2)^2)^2 = ((2 (2×2^2)^2)^2)^2:

((5^(-2)/2^3)^4 ((2 (2×2^2)^2)^2)^2 x x)/(((2^8×19^0)/5^5)^2)

2^2 = 4:

((5^(-2)/2^3)^4 ((2 (2×4)^2)^2)^2 x x)/(((2^8×19^0)/5^5)^2)

2×4 = 8:

((5^(-2)/2^3)^4 ((2×8^2)^2)^2 x x)/(((2^8×19^0)/5^5)^2)

8^2 = 64:

((5^(-2)/2^3)^4 ((2×64)^2)^2 x x)/(((2^8×19^0)/5^5)^2)

2×64 = 128:

((5^(-2)/2^3)^4 (128^2)^2 x x)/(((2^8×19^0)/5^5)^2)

((268435456 x x)/1600000000)/(65536/9765625)

The gcd of 268435456 and 1600000000 is 4096, so (x x×268435456)/1600000000 = ((4096×65536) x x)/(4096×390625) = 4096/4096×(65536 x x)/390625 = (65536 x x)/390625:

((65536 x x)/390625)/(65536/9765625)

Combine powers. (65536 x x)/390625 = (65536 x^(1 + 1))/390625:

((65536 x^(1 + 1))/390625)/(65536/9765625)

Multiply the numerator by the reciprocal of the denominator, ((65536 x^(1 + 1))/390625)/(65536/9765625) = (65536 x^(1 + 1))/390625×9765625/65536:

(65536×9765625 x^(1 + 1))/(390625×65536)

1 + 1 = 2:

(65536×9765625 x^2)/(390625×65536)

(65536 x^2×9765625)/(390625×65536) = 65536/65536×(x^2×9765625)/390625 = (x^2×9765625)/390625:

What pattern is represented by the polynomial ? 4x^2+12x+9 A. difference of two squares B. general trinomial C. perfect square t

bixtya [17]

Answer:

Option C - Perfect square trinomial.

Step-by-step explanation:

Given : Polynomial $4x^2+12x+9$

To find : What pattern is represented by the polynomial?

Solution :

First we make the polynomial in factor form,

Polynomial $4x^2+12x+9$

Since, it is not factor clearly so try to make the square.

Taking 4 common,

$=4(x^2+3x+\frac{9}{4})$

Identifying the x and y terms in the identity, $(x+y)^2=x^2+y^2+2xy$

$=4((x)^2+2\times x\times \frac{3}{2}+(\frac{3}{2})^2)$

Factor the perfect square trinomial,

$=4(x+\frac{3}{2})^2)$

Therefore, The pattern polynomial represent is perfect square trinomial.

So, Option C is correct.
