“A(5) = (5!)^3 * 1.25 = 2160000”是使用 FontVibe AI 创作的自定义风格文字效果。

Render the exact text “A(5) = (5!)^3 * 1.25 = 2160000” as a single unbroken centered line across a perfectly flat pure white #FFFFFF void. Preserve every character, parenthesis, operator, space, decimal point, and exponent notation exactly as written. Scale the isolated typography to occupy roughly 78% of the frame width, with clear white margins on all four sides. Keep the equation optically centered both horizontally and vertically, with consistent inline spacing and no line break. Use only the prescribed lettering treatment, with no added objects, scenery, texture, ground plane, border, shadow, gradient, or secondary text.
