The expression (x^n) (x^5)^3 is equivalent to x^30. What is the value of n?

Answers

Answer 1
Answer:

Answer:

n = 15

Step-by-step explanation:

(x^n)(x^5)^3 = x^30

(x^n)(x^15) = x^30

x ^ (n+15) = x^30

n + 15 = 30

n = 15

To do the question, you need to know the exponent rules, which are short cuts to be able to do exponent work.

If you raise a power to a power, then times the exponents.

If you are multiplying two terms with the same base (in this case, x; the base is the large font bottom number) then ADD the exponents.

Answers

Answer: The answer is 2.

Step-by-step explanation: If you have 2 minuses together, then that actually means a plus. -7+9 is 2.

Answer:

-7-(-9) a negative and a negative makes a positive so the new question will be -7+9 which should equal -16?

Find the missing angles in the Parallelogram

Answers

Explanation:

On the first pass, you know ...

  • g = 80° . . . vertical angles
  • I = 110° . . . vertical angles
  • m = 20° . . . alternate interior angles (WX║ZY)

Then on the second pass, you can figure ...

  • f = h = 180° -80° = 100° . . . linear angles
  • j = k = 180° -110° = 70° . . . linear angles
  • b = n = 180° -110° -m = 50° . . . sum of angles of a triangle

And the remaining angles can be determined using external angle and sum-of-angle relationships.

  • a = o = h -70° = 30°
  • c = 80° -b  = 30°
  • d = 360° -80° -20° -I = 150°
  • L = c - m = 10° . . . c and L+m are alternate interior angles
  • e = L +70°  or  110° - o = 80°
