Question #3e9c7

1 Answer

Oct 23, 2017

$16$ $16$

Explanation:

If you didn't have a calculator, you could break it up into a product of squares:

$\sqrt{256} = \sqrt{64 \cdot 4} = \sqrt{64} \cdot \sqrt{4}$ $sqrt(256)=sqrt(64*4)=sqrt(64)*sqrt(4)$

Remember taking the square root means you are thinking of a number that multiplies by itself to get the number inside, so:

$\sqrt{64} \cdot \sqrt{4} = 8 \cdot 2 = 16$ $sqrt(64)*sqrt(4)=8*2=16$
