4^a*4^a*4^a=20 a=(1+Log[4,5])/3

Nice

Input interpretation 4^(log(64, 1.25) + 0.6^_ (repeating decimal))×4^(log(64, 1.25) + 0.6^_ (repeating decimal))×4^(log(64, 1.25) + 0.6^_ (repeating decimal)) = 20 Result True Logarithmic form (log(64, 1.25) + 0.6^_ (repeating decimal)) log(4, 4) + (log(64, 1.25) + 0.6^_ (repeating decimal)) log(4, 4) + (log(64, 1.25) + 0.6^_ (repeating decimal)) log(4, 4) = log(4, 20)

{5+5+5 ➖ }=15:3^5 (x ➖ 5x+3).
