If # = square of the number
@ = cube of the number
% = reciprocal of the number
& = square root of the number
Evaluate:
9 # + 8 @ - 4 &
Show answer & explanation
Correct answer: D
Explanation
# = Square of the number
@ = Cube of the number
& = Square root of the number
Expression:
9# + 8@ - 4&
Now substitute the values of the symbols:
9# = 9² = 81
8@ = 8³ = 512
4& = √4 = 2
Hence,
81+512−2
=593−2
=591
Correct answer: 591
