Goodday Sir

The answer to number 50 NIMO olympiad 2017/2018 is _/5

Please recheck

The correct answer is option A.1

Reply with the question and I will show you how it is solved

QUESTION

Cube root of (_/5+2) + cube root of (_/5-2)

With the use of calculator , the required answer is _/5

Let p=the cube root of _/5+2 and q for _/5-2

(p+q)= cube root of _/5+2+_/5-2+3(p+q)……using properties of a cube number

p+q= cube root of 2_/5 + 3(p+q)….let p+q = x

x^3= 2_/5 +3x…..this leads to a root being

x+2=3….x=1…therefore p+q=1

Sir , Trying uisng a calculator to simplify

You’ll get _/5 as the required answer

okay. corrected.

the correct answer to number 3 is b and number 50 is e. for number 3 use simon’s favourite factoring trick

Thank you for the information

45 is d, the sequence is 1/2,2/4,3/8,4/16,5/32,6/64,7/128,8/256….
