Evaluate log base 4 of 16

4 log 16 Rewrite log(16) log (16) as log(24) log (2 4). Expand log(24) log (2 4) by moving 4 4 outside the logarithm. Rewrite log(4) log (4) as log(22) log (2 2). Expand log(22) log (2 2) by moving. log2 16 = 4, since 24 = 2 × 2 × 2 × 2 = 16. · Logarithms can also be negative: log 2 1 2 = − 1 {textstyle log _{2}!{frac {1}{2}}=

4d arta, Rewrite log(16) log (16) as log(24) log (2 4). Expand log(24) log (2 4) by moving 4 4 outside the logarithm. Rewrite log(4) log (4) as log(22) log (2 2). Expand log(22) log (2 2) by moving.
