What is the simplified form of the fifth root of x to the fourth power times the fifth root of x to the fourth power ? (1 point)

Answers

    Here's how you could solve this problem:

(root of 5)√x^4 multiplied by (root of 5)√x^4

- combine like terms

- you should get (root 5)√x^8 -> because, with the Laws of Exponents, multiplying like terms with exponents is seen to be equivalent to adding the exponents

- finally, write out x^(5/5) multiplied by x^(3/5)

- this is because you've taken out the largest multiple of 5 in the exponent that you had (5 is the largest multiple of 5 out of 8), and you subtracted 8 by 5 to get the remaining exponent of the other term

- simply exponents, and you're done :D :D :D :D :D

Q5: What is the measure of JH?Question 5 options:

12

33.33

Answers

Answer:

The answer to your question is 12

Step-by-step explanation:

Use proportion to solve this problem

Equation

           (JH)/(MQ) = (JL)/(MP)

Substitution

           (x)/(20) = (15)/(25)

                              25x = 15(20)

                              25x = 300

                                  x = 300 / 25

                                  x = 12

                                  x = JH = 12

Answer:

the correct answer is option A. 12

Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (–1 + i) + (21 + 5i)?

Answers

Answer:

The given expression is (–1 + i) + (21 + 5i) : It demonstrates the use of the commutative property of addition in the first step of simplifying the expression. The property of commutativity is that the bracket can change its position i.e. (i + 21 )+ (5i-1)

Step-by-step explanation:

Answer:   angle AOB = 40 degrees

====================================================

Explanation:

The smaller angles AOB and BOC combine to the largest angle AOC

By the angle addition postulate, we can say,

(angleAOB) + (angleBOC) = (angleAOC)

(3x+4) + (8x-28) = 108

11x-24 = 108

11x = 108+24 .... adding 24 to both sides

11x = 132

x = 132/11 .... dividing both sides by 11

x = 12

We can use this x value to find each angle

angle AOB = 3x+4 = 3*12+4 = 40 degrees

angle BOC = 8x-28 = 8*12-28 = 68 degrees

As a check,

(angleAOB)+(angleBOC) = (40)+(68) = 108

which matches with the measure of angle AOC. This confirms our answers.

Answer:

AOB = 40

Step-by-step explanation:

AOC = 108 \n </p><p>AOB = 3x + 4 \n </p><p>BOC = 8x - 28 \n but \: AOB +BOC =AOC \n 3x + 4 + 8x - 28 = 108\n 11x = 132 \n x = 12\n AOB = 3x + 4 = 3(12) + 4 \n AOB = 40
