(16−−√)squared =

Question

in simplest form.

Answer 1

Starting with (16−−√)squared:

(16−−√)squared = (16−−√)(16−−√) [Using the exponent rule for multiplication]

= (16)(16) - (16)(−−√) - (−−√)(16) + (−−√)(−−√) [Using FOIL method]

= 256 - 32√ + 32√ - 16 [Simplifying middle terms]

= 240 [Simplifying the constants]

Therefore, (16−−√)squared = 240 in simplest form.
