togundeji · Answer

The answer is 60

zepdrix · Answer

Multiply the `two` numbers together,
then take the `second` root.

$\large\rm 6\cdot10=60$
$\large\rm \sqrt{60}=?$

togundeji · Answer

Is it 66

zepdrix · Answer

66 is not one of your options.
I'm not sure what you're asking.

You're asking if the square root of 60 is equal to 66..?

togundeji · Answer

I don't really understand this either @zepdrix

zepdrix · Answer

To find geometric mean,
you multiply the numbers together, and take their square root.

$\large\rm \sqrt{6\cdot10}=\sqrt{60}$
60 contains a perfect square, which can be removed from the root.

zepdrix · Answer

$$\large\rm \sqrt{60}=\sqrt{4\cdot15}=\sqrt{4}\cdot\sqrt{15}$$

zepdrix · Answer

Square root of 4?

togundeji · Answer

2 @zepdrix

zepdrix · Answer

$$\large\rm \sqrt{60}=2\cdot\sqrt{15}$$k good.

togundeji · Answer

So the answer is 60?
