Answer:
ans-----17.32+12.3=29.6 or nearly 30
Step-by-step explanation:
x=2^1/3+1/2^1/3
x^3=(2^1/3+1/2^1/3)^3=8.66086(by using calculator,little complex)
(2^1/3)^3=2
1/(2^1/3)=1/2
6(X)=6(2.05)
=12.3
2x^3=2(8.66)=17.32
can it be done without calculator
use should know only 2^1/3 value
plz mark as brainliest
if u know that value it is very easy
yes it can. resend for a full solution
but the sign is wrong. by this i mean x^3 - 6x
2x^3 - x^6
yup
i agree with u. if he does not change the sign, then the question is meaningless. who wants to use a calculator?

i think you should change the sign from minus to plus. otherwise there is no meaning with the question because you have to use the calculated
calculator
and it is NOT the meaning here to use a calculator
