Question

i need help 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?

Answer 1

HI!!

Answer 2

hi i need help

Answer 3

\[\sqrt[5]{x^4}\times \sqrt[5]{x^4}\]??

Answer 4

yess

Answer 5

first add up the exponents inside the radical (i.e. multiply) and get
\[\sqrt[5]{x^8}\] but that is not the final answer

Answer 6

10 /8 i add all the exponents

Answer 7

since 5 goes in to 8 one time, with a remainder of 3, the final answer is
\[x^1\sqrt[5]{x^3}\] or just
\[x\sqrt[5]{x^3}\]

Answer 8

you have it upside down dear, and the addition is not quite right \[\huge x^{\frac{4}{5}}\times x^{\frac{4}{5}}=x^{\frac{8}{5}}\] since
\[\huge \frac{4}{5}+\frac{4}{5}=\frac{8}{5}=1\tfrac{3}{5}\]

Answer 9

ohh i seee noww......

Answer 10

Find the solution of 5 times the square root of the quantity of x plus 7 equals negative 10, and determine if it is an extraneous solution.

x = −3; extraneous
x = −3; not extraneous
x = 11; extraneous
x = 11; not extraneous

Answer 11

that may be a good explanation of why the answer is \[x\sqrt[5]{x^3}\]

Answer 12

my friend got A and i think is C who's right ?

Answer 13

it is certainly extraneous, i.e. there is no solution
so why should you have to try and find it i have no idea

Answer 14

i guess they want you to square both sides
\[25(x+7)=100\]

Answer 15

divide by 25 get
\[x+7=4\] so \[x=-3\] really it is a bad question though

Answer 16

oh sorry, your friend is right

Answer 17

oh i used the wrong operation :(

Answer 18

Given the functions f(x) = −2x − 1 and g(x) = −3x + 4, which operation results in the smallest coefficient on the x term?

Addition
Subtraction
Multiplication
Two operations result in the same coefficient

Answer 19

this is another one we are arguing about. she thinks its B i go with D

Answer 20

ya'll both wrong

Answer 21

ohhhhh why?

Answer 22

add and get \(-5x+3\)
subtract and get who knows because we don't know which one gets subtracted from which, but either way you will not get \(-5x\) you will get either \(-x\) or \(x\)

Answer 23

oh wait, i didn't multiply yet

Answer 24

i read to her what you wrote she thinks its A

Answer 25

if you multiply you get \[6 x^2-5 x-4\]

Answer 26

so the answer is actually D, two operations result in the same coefficient, addition and multiplication

Answer 27

lol soo i was right

Answer 28

let me guess
FLVS?

Answer 29

lol yeah im helping her. shes been struggling

Answer 30

i can always tell flvs questions by how bad they are

Answer 31

lol finally someone agrees... lol but thanks again for helping me i'll fan you okok
