It will depend on where you put your parentheses. Root 7 -( 1/root 7) is different from (root 7-1)/root 7. * * * * * True, but a more helpful answer: [sqrt(7) - 1]/[sqrt(7) + 1] - [sqrt(7) + 1]/[sqrt(7) - 1] Multiplying the numerator and denominator of the first fraction by [sqrt(7) - 1] and the second fraction by [sqrt(7) + 1] = [sqrt(7) - 1]2/[7 - 1] - [sqrt(7) + 1]2/[7 - 1] =[7 - 2*sqrt(7) + 1]/6 - [7 + 2*sqrt(7) + 1]/6 = 16/6 = 8/3
√441 = √(3^2 × 7^2) = 3 × 7.
7 divided by 2/3 = 7 x 3/2 = 21/2
It doesn't factor neatly. If you solve it, you get the square root of 12/7 which is either 2 times the square root of 3/7 or -2 times the square root of 3/7
(-2-3)2+(7-7)2 = 25 and the square root of this is the distance which is 5
(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

7 ÷ 2 + (√3) = 5.232050808
5 square root 7 because 3 square root of 28 goes from 3 square root of 28 to 3 square root of 7 and 4 which then 4 condenses down to 2 and you add that to 3 then you get 5 square root of 7
√441 = √(3^2 × 7^2) = 3 × 7.

7 divided by 2/3 = 7 x 3/2 = 21/2
First find the factors of 196. It's even, so divide by 2, giving 98. It's still even, so divide by 2, giving 49. This is odd, so look for an odd number that will divide it. Bingo ! 7 divides it , leaving 7 as the last factor. The factors are 2 2 7 7. Group these in pairs; 2 x 7 and 2 x 7; 14 x 14 = 196 so, the square root of 196 is 14.

(-2-3)2+(7-7)2 = 25 and the square root of this is the distance which is 5
18 ÷ 3 x 2 - 7 = 5
