Question

Simplify - 2\sqrt[3]{{11}} - \left( { - 8\sqrt[4]{3}} \right) - 8\sqrt[4]{3} + 15\sqrt[3]{{11}}. Write your answer in simplest radical form.

Answer 1

\[- 2\sqrt[3]{{11}} - \left( { - 8\sqrt[4]{3}} \right) - 8\sqrt[4]{3} + 15\sqrt[3]{{11}}.\]

Answer 2

do u know how to simplify this ?

Answer 3

group the like terms \[- 2\sqrt[3]{{11}} - \left( { - 8\sqrt[4]{3}} \right) - 8\sqrt[4]{3} + 15\sqrt[3]{{11}}\\
=(-2+15)\sqrt[3]{11}+\big(-(-8)-8\big)\sqrt[4]{3}\\=\]
then simplify the terms in brackets

Answer 4

what did you end up

Answer 5

you tell me

Answer 6

Im not smart.

Answer 7

(−2+15) = ?

Answer 8

13

Answer 9

good ,

what about
(−(−8)−8)

Answer 10

if it looks a bit confusing try to simplify this bit first

-(-8)= ?

Answer 11

-8?

Answer 12

or just 8

Answer 13

-(-8)=+8

Answer 14

so what is

(−(−8)−8) = ?

Answer 15

64..?

Answer 16

we just said −(−8)=8


so (−(−8)−8) = (+8−8) = (8−8) = ?

Answer 17

so i solve this ?

Answer 18

u there

Answer 19

i am here,

Answer 20

what is eight minus eight?

Answer 21

0

Answer 22

so , can you work out the final answer now/

Answer 23

could u tell me the answer and explain the steps? that helps me a lot better

Answer 24

if you read all of the above posts slowly, you will be able to answer the question your self

Answer 25

ok what about the 3 and 11 ? and 4 and 3

Answer 26

???

Answer 27

those bits cannot be simplified , they will be in your final answer

Answer 28

so, 13+0 then you sqaure the other numbers

Answer 29

after u simplify

Answer 30

\[- 2\sqrt[3]{{11}} - \left( { - 8\sqrt[4]{3}} \right) - 8\sqrt[4]{3} + 15\sqrt[3]{{11}}\\
=(-2+15)\sqrt[3]{11}+\big(-(-8)-8\big)\sqrt[4]{3}\\=(13)\sqrt[3]{11}+\big(0\big)\sqrt[4]{3}\\=\]

[dont square anything]

Answer 31

dont you do 11*11*11

Answer 32

next
