When expressed in a decimal form, which of the following numbers will be nonterminating as well as non-repeating?
Explanation:
We need to check options.
Option (a): π21π+1-π2 = 12+π2-π2 = 12 = 0.5 (terminating)
Option (b): sin21° + sin22° + … + sin288° + sin289° = sin21° + sin22° + … + sin245° + … + cos22° + cos21° = 44 + ½ = 44.5 (terminating)
Option (c): 72933+227 = 93+227 = 3 + 22/7 (terminating)
Option (d): 4-π[1+π4+π42+π43+... inifinite terms] = 4-π11-π4 = 4 (non-terminating)
Option (e): 232-42+3 = 6 - 4 + √3 = 2 + √3 (non-terminating and non-repeating)
Hence, option (e).
