Question

(-2x+6)^1/5=(-8+10x)^1/5

Answer 1

please help!

Answer 2

anyone know how to do this?

Answer 3

Since they are bot to the 1/5 power you can eliminate that and solve for (-2x+6) = (-8+10x) Do you need help with that?

Answer 4

yes please

Answer 5

do you use foil?

Answer 6

-2x +6 = -8 +10x. We need to get the variables ( x values) to one side of the equation and the constants to the other side. So how would you do that?

Answer 7

foil is for multiplying

Answer 8

okay so you just add 2 to each side and add 8 to the 6

Answer 9

Yes and solve for x. What do you get?

Answer 10

so then i get 14+12x?

Answer 11

and then divide 12 to each side?

Answer 12

i mean 14=12x

Answer 13

yes and divide both sides by 12

Answer 14

okay but why do you just forget the 1/5?

Answer 15

Hold on

Answer 16

Sorry had to take care of something. In equations that have the same exponent they would cancel out. It is a rule.

Answer 17

oh okay thanks!
