you just say a fun fact about math
X^0.5 ALWAYS equals the square root of X. Example:
5^0.5 - Google Search.png
SqRoot of 5 - Google Search.png
 
Uh yea that makes sense cuz of exponent rules. Anything to the half power is the same as the square root of that number.Anything to the one third power is the same thing as the cube root of that number. Anything to the one fourth of that number is the same thing as the 4th root of that number... etc. You get the idea.

You can multiply any number by 11 quickly in your head by adding the two digits together and sticking the sum in the middle. Ex. if u have 52 x 11 then u do 5+2=7 and put 7 in the middle of the 52 to get 572. It always works! It harder though when u have a sum greater than 9, but still is possible.
