Question

Solve:
r5- 6 = -1
A) r = 1
B) r = 5
C) r = 10
D) r = 25

Answer 1

Please explain (in words) what you mean by "r5." For example, are you referring to multiplication or to exponentiation? What is the goal of this problem?

Answer 2

r/5

Answer 3

Makes a big difference!

So: r/5 - 6 = - 1.

What step could you take to isolate r/5 on the left side?

Answer 4

Yes thats right

Answer 5

Add up the numbers

Answer 6

Try adding 6 to both sides. Your result?

Answer 7

1

Answer 8

Where's the other side of your equation?

Write out the whole equation, please.

Answer 9

thats it

Answer 10

Not so. You started with an equation and if your answer is correct, you'll end with an eqatuion.

You began with r/5-6=-1 and added 6 to both sides.

What does your equation look like now?

Answer 11

I dont understand

Answer 12

Let's write out your equation: r/5 - 6 = -1
Add 6 to both sides: +6 = +6
____________________
r/5 = 5

Answer 13

So now r/5 = 5.

What would you do next, to isolate r?

Answer 14

divide

Answer 15

Multiply both sides of this latest equation by 5:

\[5(r/5)=5(5)\]

Answer 16

Please finish this work.

Answer 17

Remember: multiplication is the inverse operation of division.

Answer 18

Still interested in finishing this problem?

If something's not clear to you, please ask questions as needed.

Answer 19

Yea i dont understand...

Answer 20

its A, r=1

Answer 21

Hello no direct answers please :D

Answer 22

First Add 6 to both sides
r^5=−1+6

Answer 23

Simplify −1+6−1+6 to 5
r^5=5

Answer 24

Take the 5th root of both sides
r=5√5

Answer 25

which gives you 1.379 which rounded gets you 1 which gets you A :D

Answer 26

We have a problem here:
Original post was "r5-6=-1.
I asked QueSmith for clarification. He said he meant r/5.
Now you @KJSaif , are guessing that QueSmith meant

Answer 27

i don't know i said 5√5. Take the 5th root of both sides r=5√5 was i wrong?

Answer 28

@KJSaif

You told others to not give a direct answer, yet you gave a direct answer yourself right after that.

Also, your answer was wrong.

The asker (QueSmith) clarified that the question was:
r/5 - 6 = -1

NOT

r^5 - 6 = -1

And then you gave the answer first as \( 5\sqrt{5}\) when the correct answer to r^5 - 6 = -1 should actually be \(\sqrt[5]{5}\)

Also, you were solving the wrong equation, so it really doesn't matter if the answer you gave was correct or wrong since it wouldn't answer the question given.

Answer 29

Not to forget the fact that you gave an answer that wasn't even in the answer choices.

Answer 30

i didn't give direct i explained

Answer 31

maybe i messed up this question.

Answer 32

stop

Answer 33

wow thanks for ruining my day im leaving for a year because of YOU
