7^2 = 49 or, just factor out to 7
8th root
= 1.626576562
The square root of 28 minus the squared root of 7 =±2.64575131

(3 root 7) squared = (3 root 7) (3 root 7) = (3x 3) ( sq root 7 x 7) = 9 x sq root 49 = 9 x 7 = 63
eight squared=64 eight to the negative tenth power= the tenth root of 8 if multiplied together= the eighth root of 8
The same as the 8th decimal place of Pi itself.
The square root that lies between 6 and 7 is approximately 6.5. To be more precise, the square root of 42.25 (which is 6.5 squared) is exactly 6.5. Thus, any number whose square falls between 36 (6 squared) and 49 (7 squared) will have a square root between 6 and 7.
-7.. square root cancels out square
Huh? The square root of 49 is 7. 4 squared is 16 Take it from there
21.
