I believe that an answer without an explanation is no help. This answer, however,
is the result of the combination of the seat of my pants and the top of my head,
so I'm afraid that no cogent explanation can be given. Here's the answer:

The factored form of [ 16x - 2x - 3 ] is (2x-1)(8x + 3) .

Solve Tan^2x/2-2 cos x = 1 for 0 < or equal to theta < greater or equal to 1.

mixer [17]

Answer:

x = theta = 0°

Step-by-step explanation:

Given the trigonometry function

Tan²x/2-2 cos x = 1

Tan²x-4cosx = 2 ... 1

From trigonometry identity

Sec²x = tan²x+1

tan²x = sec²x-1 ... 2

Substituting 2 into 1, we have:

sec²x-1 -4cosx = 2

Note that secx = 1/cosx

1/cos²x - 1 - 4cosx = 2

Let cosx. = P

1/P² - 1 - 4P = 2

1-P²-4P³ = 2P²

4P³+2P²+P²-1 = 0

4P³+3P² = 1

P²(4P+3) = 1

P² = 1 and 4P+3 = 1

P = ±1 and P = -3/4

Since cosx = P

If P = 1

Cosx = 1

x = arccos1

x = 0°

If x = -1

cosx = -1

x = arccos(-1)

x = 180°

Since our angle must be between 0 and 1 therefore x = 0°

The number (answer) is 2592.
Check your answer:
(substitute the numbers to see if they will equal 2592: 2^5 is 32 and 9^2 is 81)
Now subsitute it into A^B*C^D: 32*81 is 2592.
