we're pacifying the square root of 0.25 x squared. Since we're square rooting, we should try to write our expression. In terms of perfect squares. 0.25 is the same thing as 0.5. I swear and X squared is obviously X square. There is a property with oh, radicals that allows us to break up a product. So this is the same thing as the square root of point five square times the square root of X squared. So this whole expression would be equal to, um once we account for our square roots. Counter acting are perfect squares in canceling them out 0.5 times x, so the square root of 0.25 x squared would be equal to 0.5 x.

The number 2 is also the smallest & first prime number (since every other even number is divisible by two).

If you write pi (to the first two decimal places of 3.14) backwards, in big, block letters it actually reads "PIE".
