4ax3
4ax3 is commonly read as the algebraic term 4a x^3, where a and x denote variables or constants and x^3 indicates x raised to the third power. In plain text, the caret is sometimes omitted, leading to the form 4ax3; to avoid ambiguity, writers often express it as 4a x^3 or 4ax^3.
Meaning: If a is constant and x is a variable, 4a x^3 is a monomial of degree
Calculus: If a is constant, d/dx of 4a x^3 = 12 a x^2. If a depends on x,
Examples: With a=2 and x=5, the expression evaluates to 42125 = 1000. In a polynomial P(x) = 4a
Alternate uses: The string 4ax3 may also appear as a product code or identifier in non-mathematical contexts
