for example now:
• √9 (9) = √ (9) × (9) = 27 but √9e = √ (9 × e)
• sinπcosπ = (sin (π)) × (cos (π)) but sin2πcosπ = (sin (2 × π)) × (cos (π))
• cos2π = cos (2 × π)
• 2 ^ 2e = 2 ^ (2e) but 2 ^ 2lg100 = 2 ^ 2 × lg100
• √lg10000 (1E5) = √ (log (10000)) × (1E5)
• lg4! 4 = lg (4!) × 4
• lg4! Lg100 = lg (4!) × lg100
In general, if the function argument is an implicit product (unsigned multiply) of numbers, then all numbers are included in the function argument
•••••••••
• 2³! = (2 ^ 3)!
• lg100³ = lg100 ^ 3 = (lg100) ^ 3
• lg100³! = (lg100³)!
