What is the geometric mean of 6 and 15
Accepted Solution
A:
Answer:[tex]\large\boxed{3\sqrt{10}\approx(3)(3.16)=9.48}[/tex]Step-by-step explanation:[tex]\text{The geometric mean formula:}\\\\\sqrt[n]{a_1\cdot a_2\cdot a_3\cdot...\cdot a_n}\\\\\text{We have}\ 6\ \text{and}\ 15.\ \text{Substitute:}\\\\\sqrt{(6)(15)}=\sqrt{90}=\sqrt{(9)(10)}=\sqrt9\cdot\sqrt{10}=3\sqrt{10}\approx(3)(3.16)=9.48[/tex]
