first find value of a
a=√2-1
subtract
a=√1
then sq root of 1 = 1
a=1
replace a's with 1
(a-1/a)³ = (1-1/1)³
according to BIDMAS/BODMAS, divide first, 1 divided by 1 equals 1
(1-1)³
1 minus 1 equals 0
(0)³
0x0x0=0
so the ans is 0
if u understood plz mark me brainliest if u didnt plz dont hesitate to ask
