Answer:
0.8
Step-by-step explanation:
First, let's solve it without the decimal. So it would be this:
[tex]\sqrt{64}[/tex]. That one is pretty easy. Think about it. 8^2 = 64 so the sqare root of 64 is 8.
Now, for the decimal. It's 0.64. That's into the hundreths of 2 decimal spots. To find the square root are answer will be 8, moved one slot over.
So our answer is:
[tex]\sqrt{0.64} = 0.8[/tex]
