Question

write radical expression in exponential form: 8 divided by 7th root of x to 15th power

Answer 1

so like an example if squarrot of x is equal x on exponent 1/2
where the denominator 2 is the indice of root

hope so much that now using this example you will can solveing your exercise easy

ok ?

good luck

bye

Answer 2

is it 8x7/15?

Answer 3

so if squarroot of x is x on exponent 1/2 than 7th root of x on 15th power how will be right ?

Answer 4

I don't understand what you are saying

Answer 5

how you write 7th root of x ?

Answer 6

sq rt. sign with x underneath and 7 outside to left

Answer 7

\[\sqrt[7]{x}\]

Answer 8

yes but x has exponent of 15

Answer 9

so than how will rewrite you this using exponents ?

Answer 10

x15/7

Answer 11

ok i understand it but i wann you understand it step by step

ok ?

Answer 12

what am I missing?

Answer 13

so when there are 7th root of x^15 how can you simplifie it ? or what can you factoriz out from root ?

Answer 14

oh- what can be factored out of 7-nothing?

Answer 15

so check it please

how can you rewrite it x on exponent 15 using exponent of 7 ?

Answer 16

no idea

Answer 17

why ? this is very very easy

Answer 18

for u it is. not sure what u are asking

Answer 19

when 15=7+7+1

Answer 20

or for your easy understanding

x^15 =x^7 *x^7 *x

right ?

Answer 21

but I don't understand what u want me do with the factoring. my answer should have 7/15 or 15/7 in it and if you factor out it won't

Answer 22

yes-see I need the easy explanation

Answer 23

so x^15 = (x^2)^7 *x

ok ?

Answer 24

yes

Answer 25

so than how you calcule 7th root of x^15 ?

Answer 26

why do I need to calculate 7th rt of x^15? Don't I have to eliminate the denominator and multiply the numerator by that to get answer?

Answer 27

ok

so you need to write the 8/(7th root of x^15) in a simplified form ?

Answer 28

my question states in exponential form but I guess it is simplified form. My choices have no denom. only numerator 8x with ^either -15/7 or -7/15 or 7/15 or 15/7. I think it is 8x^7/15

Answer 29

so the 7th root of x on power 15 how you can write it using exponents ?

Answer 30

15/7?

Answer 31

so than will be x^(15/7)

yes ?

Answer 32

yes but I have to multiply x^15/7 by x^7/15 to remove from denom.

Answer 33

so than your exercise will be

8
--------
x^(15/7)

ok ?

Answer 34

but I can't leave that in the denomin

Answer 35

so when there are x^(-1) = ?

Answer 36

1/x

Answer 37

yes ,right

Answer 38

what is the point you r making

Answer 39

so than from this resulted that your exercise will be ???

Answer 40

I thought it would be 8x^7/15

Answer 41

so there are

8
-------- = ?
x^(15/7)

using this example of 1/x = x^(-1)

Answer 42

do I not multiply denom by x ^7/15 to eliminate it and then multip. numerator by same number?

Answer 43

so this you need to do it when you need to rationalize the denominator ,but here now you need to rewrite this exercise in a simplified form using exponents

ok ?

Answer 44

will if the answer doesn't have a denominator then I am also rationalizing aren't I?

Answer 45

yes this is right the answer not will have denominator because how in case of 1/x using exponent with sign minus you can rewrite it like x on exponent minus 1 so the same you need to do in this case of this exercise too

ok ?

Answer 46

\[8x \frac{ -15 }{ 7 }\] is the answer
