Simplifying (106p3)(318p)(10\sqrt{6p^3})(3\sqrt{18p})

Multiply and simplify a product of two square roots that each have numerical coefficients and variable radicands, producing a result with a large coefficient.

(106p3)(318p)(10\sqrt{6p^3})(3\sqrt{18p})

Multiply the coefficients together and multiply the radicands together:

(106p3)(318p)=30108p4(10\sqrt{6p^3})(3\sqrt{18p}) = 30\sqrt{108p^4}

The coefficients give 103=3010 \cdot 3 = 30. The radicands give 6p318p=108p46p^3 \cdot 18p = 108p^4 (since 618=1086 \cdot 18 = 108 and p3p=p4p^3 \cdot p = p^4). Now simplify the radical by extracting perfect square factors. The largest perfect square dividing 108108 is 3636, and p4p^4 is a perfect square:

30108p4=3036p43=306p23=180p2330\sqrt{108p^4} = 30 \cdot \sqrt{36p^4} \cdot \sqrt{3} = 30 \cdot 6p^2 \cdot \sqrt{3} = 180p^2\sqrt{3}

The simplified result is 180p23180p^2\sqrt{3}. This example combines three multiplicative components — the product of the outside coefficients (3030), the integer extracted from the simplified radical (6p26p^2), and the remaining radical (3\sqrt{3}) — which are all multiplied together to form the final answer.
