Answer:

  • 20°

Step-by-step explanation:

Which expression is equivalent to x^6y^8/x²y²
Kipish [7]

Answer:

For this case we have the following expression:

  (x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2

Rewriting and for power properties we have:

  (x ^ 18y ^ 24) / x ^ 2y ^ 2

  (x ^ (18-2) y ^ (24-2))

  (x ^ 16y ^ 22)

Answer:

The equivalent expression is given by:

  (x ^ 16y ^ 22)

If sin (x-3)° = cos (2x + 6)°, then what is the value of x?
Travka [436]

Answer:

if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.

----------

Note: sin and cos are complementary functions....

sin(x) = cos (90-x)

-------------------

Your Problem:

sin(x-3) = cos(90-(x-3))

Equation:

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29
