Simplifying 25n65n+45n2\sqrt{5n} - 6\sqrt{5n} + 4\sqrt{5n}

To simplify 25n65n+45n2\sqrt{5n} - 6\sqrt{5n} + 4\sqrt{5n}, observe that all three terms are like square roots because they share the identical radicand 5n5n. You can combine them by summing their coefficients: 26+4=02 - 6 + 4 = 0. Multiplying this zero coefficient by the radical yields 00. Thus, the entire expression simplifies to 00. This is directly comparable to the algebraic simplification of like terms where 2x6x+4x2x - 6x + 4x results in 0x0x, which simplifies to 00.
