The ratio of the sum of m and n terms of an AP is m^2 :n^2 ,show that the ratio of the mth and nth term is ( 2m-1):(2n-1). Can this qn be done this way ??

I dont know what the answer is exactly

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
