May be I am misunderstanding something
The equation adds to
8 sqrt 4
or do you mean to say
third root of 4 and
4th root of four

root question
Source: Beat The GMAT — Problem Solving |
this is weird !!
Alright ! root 4 is taken as common factor
root 4(1+3+4)
8 root 4
so obviously it is greater than 4 !! i mean !!wat is that question is expecting out of this !!

hey guys
i am sorry for my earlier post. i am posting it again, i hope this raises no question anymore--
M = square root 4 + cube root 4 + fourth root of 4, then the value of M is:
a) less than 3
b) equal to 3
c) between 3 and 4
d) equal to 4
e) greater than 4 - answer

i agree totally...let me try for secound choice,
that sounds mroe logical
root 4 will be 2
4root4 will be sqrt(2) which is 1.414
sum will be 3.414
now 3root4 will lie between 2 and 1.414
so sum will always be greater than 4
hope this helps!!!
square root 4 + cube root 4 + fourth root of 4
The square root of 4 is 2. That's simple.
The fourth root of 4 = the square root of 2 since 4 is 2 squared.
The cube root of 4 will be < square root of 4 and > fourth root of 4.
= 2 + cube root 4 + square root of 2
This means 2 + a little less than 2 + a little more less than 2 > 4
