Question

Perform the operation(s)    ( − 8 )  2 ( \sqrt { - 8 } )  ^ { 2 } ( − 8 ​ )  2   and write the result in standard form.A)    64 64 64 B)    8 i 8 i 8 i C) 8D)    − 8 - 8 − 8 E)    − 64 - 64 − 64

Lindsey Perry · Accepted Answer

Final Answer : D, Explanation :   ( − 8 ) 2 = ( 2 i ) 2 = 4 i 2 = 4 ( − 1 ) = − 4 ( \sqrt { - 8 } ) ^ { 2 } = (2i)^2 = 4i^2 = 4(-1) = -4 ( − 8 ​ ) 2 = ( 2 i ) 2 = 4 i 2 = 4 ( − 1 ) = − 4 Therefore, the answer is option D,   − 8 -8 − 8  , in standard form.
