A conceptual visualization of mathematical operations involving square roots. The scene shows three separate, distinct square roots, colored differently for clarity and interpretation. First square is depicted as the square root of 32a, painted in blue. The second as the square root of 50a, represented in red. The third and final one is the square root of 18a, shown in green. The squares are not touching, and they occupy a landscape of white parchment paper, highlighting the main theme of this conceptual geometric illustration.

Express √32a- √50a+√18a in simplest surd form

√32a- √50a+√18a

= √(16 * 2 * a) - √(25 * 2 * a) + √(9 * 2 * a)

= 4√2a - 5√2a + 3√2a

= 2√2a
