3sqrt(x) - 5 = 3
Add 5 to both sides: 3*sqrt(x) = 8
Divide both sides by 3: sqrt(x) = 8/3
Square both sides: x = 64/9
Ahexagon = 3sqrt(3)s2/2 = 3sqrt(3)(82)/2 = 96sqrt(3)
3sqrt(80)= 26.8======
2n - 3 = 5Add 3 to each side:2n = 8Divide each side by 2:n = 4
(x-5)^(1/3) = 3; (x-5) = 3^3 = 27; x = 27+5=32
x = 0 & y = -3
3sqrt(3) - sqrt(45) + 3sqrt(13)= 3sqrt(3) - 3sqrt(5) + 3sqrt(13) = 3*[sqrt(3) - sqrt(5) + sqrt(13)] where the expression in parenthesis cannot be simplified.The value is 9.3046, approx.
Ahexagon = 3sqrt(3)s2/2 = 3sqrt(3)(82)/2 = 96sqrt(3)
sqrt(18) = sqrt(9*2)= sqrt(9)*sqrt(2) = +/-3sqrt(2) -3sqrt(2) - 7sqrt(18) = -3sqrt(2) -/+7*3sqrt(2) = -3sqrt(2) -/+21sqrt(2) = -24sqrt(2) or 18sqrt(2).
Well if you have to show you're work, you do 7X123 which equals 861, and then you do 861-3 and that equals 858
3sqrt(- 1 ) = 3i --------
3sqrt(80)= 26.8======
3sqrt(5) = 6.708 approx.
3sqrt(- 1 ) = 3i --------

2n - 3 = 5Add 3 to each side:2n = 8Divide each side by 2:n = 4
(x-5)^(1/3) = 3; (x-5) = 3^3 = 27; x = 27+5=32
Factor under the radical. sqrt(72) sqrt(3^2 * 8) 3sqrt(8) 3sqrt(2^2 * 2) 6sqrt(2) check and you see that sqrt(72) and 6sqrt(2) are equivalent
