You know the formula, Log _an p^m= m/n log_ap

Applying the formula,

Log₂x + 1/2 Log₂x + 1/4 Log₂x = 21/4

Taking Log₂x common,

(1 + 1/2 + 1/4) Log₂x = 21/4

(7/4) Log₂x = 21/4

Log₂x = 3

X =2³ = 8

 Applying the formula,

Log2x + 1/2 Log2x + 1/4

Log2x = 21/4

Taking Log2x common, (1 + 1/2 + 1/4) Log2x = 21/4 (7/4)

Log2x = 21/4

Log2x = 3 X =23 = 8
