log2 b = x
How to find logarithm log2 b = x?
log2 b is logarithm of b to base 2 (binary logarithm)
x is the exponent to which you need to raise base 2 to get b.
log2 b = x ⇔ 2x = b
Symbol: log 2 b = lb b = log 2 (b) = log (b, 2)
Examples:
log 2 8 = x ⇔ 2x = 8 ⇒ x = 3
log 2 64 = x ⇔ 2x = 64 ⇒ x = 6
log 2 256 = x ⇔ 2x = 256 ⇒ x = 8
