Is anyone good at Simplifying Radical Expressions?

Mathematics
1 answer:
Lynna [10]3 years ago

All you really have to do is find the prime factorization of the term.  And for every pair of like factors you can move that term outside of the radical sign (for square roots)  If you were doing cube roots you would need to find threesomes of factors... for example..

20^(1/2)

pf 20=2*2*5  so you have two twos so you can simplify to 2(5)^(1/2)

108^(1/3)

pf 108=2*2*3*3*3 so you have 3^3 so you can simplify to 3(4)^(1/3)

Solve the equation -5 = c/7
sweet-ann [11.9K]
Multiply both sides by 7.

-5 * 7 = c/7 * 7

-5 * 7 = c

c = -35

Your final answer is c = -35.

write the equation in slope-intercept form of the line that has a slope of -3 and contains the point (4, -5).
Novosadov [1.4K]
You can answer this question by plugging the given values into point-slope form, which is y - y_{1} = m (x - x_{1}). M will represent slope and x_{1} and y_{1} will represent the x and y coordinates.

   y - y_{1} = m (x - x_{1})   Substitute in the values
y - (-5) = 4 (m - 4)   Cancel out the -(-5)
   y + 5 = 4 (m - 4)   Use the Distributive Property
   y + 5 = 4m - 16    Subtract 5 from both sides
       
         y = 4m - 21

Please help thank you so so so much <br><br> there is more than one answer
Luden [163]

Answer:

B and C work. A and D do not.

Step-by-step explanation:

This is one of those questions that you have to go through each answer to see what the results are. You don't have to go far to eliminate A and D so let's do that first.

A]

5n + 6

Let n = 1

5(1) + 6

5 + 6= 11

However there is trouble beginning with n = 2

5*2 + 6

10 + 6

16     All you need is one wrong answer and the choice is toast. So A won't work.

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

Try D

6(n - 1)+ 5

n=0

6*(-1) + 5

-6 + 5

- 1

And D has been eliminated with just 1 attempt. n= 2 or n = 1 would be even worse.  D is not one of the answers.

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

B

Let n = 1

6(1) + 5

6 + 5

11 The first term works.

n = 2

6*(2) + 5

12 + 5

17 and n = 2 works as well. Just in case it is hard to believe, let's try n = 3 because so far, everything is fine.

n = 3

6*(3) + 5

18 + 5

23 And this also works. I'll let you deal with n = 4

========

C

n = 0

6(0 + 1) + 5

6*1 + 5

6 + 5

11

n = 1

6(1 + 1) + 5

6*2 + 5

12 + 5

17 which works.

So C is an answer.
