Question

geometric mean of each pair of numbers; 4 and 10; 4 and 49; 5 and 125; 1/2 and 2; and square root of 28 and square root of 7

Answer 1

• 2√10
• 14
• 25
• 1
• 14

Explanation:

The geometric mean of "a" and "b" is the root of their product:

geometric mean = √(ab)

Then your means are ...

√(4·10) = √40 = 2√10 ≈ 6.3246

√(4·49) = 2·7 = 14

√(5·125) = √625 = 25

√((1/2)·2) = √1 = 1

√(28·7) = √196 = 14
