To simplify the expression 5√8x³ + 3√18x³, we first need to simplify the square root terms.
√8 can be simplified as 2√2, as 2 * 2 = 4 and 4 * 2 = 8.
√18 can be simplified as 3√2, as 3 * 3 = 9 and 9 * 2 = 18.
Now the expression becomes:
5(2√2)x³ + 3(3√2)x³
= 10√2x³ + 9√2x³
= (10 + 9)√2x³
= 19√2x³
Therefore, 5√8x³ + 3√18x³ simplifies to 19√2x³.
