-7.
5x-3 = -15
-15-4\4= -16
-16 + 9 = -7
Here, we know, √225 = 25 (perfect squared)
whereas √223 is not a perfect squared.
So, √225 would be "Rational" whereas √223 would be "Irrational" by the nature.
Hope this helps!
Write i in trigonometric form. Since |i| = 1 and arg(i) = π/2, we have
i = exp(i π/2) = cos(π/2) + i sin(π/2)
By DeMoivre's theorem,
i² = exp(i π/2)² = exp(i π) = cos(π) + i sin(π)
and it follows that i² = -1 since cos(π) = -1 and sin(π) = 0.
