" 3."(2+3i)(4-5i)=?

Evaluate (2+3i)(4-5i).

(3+5i)/(2-3i)

Inverse of (3+4i)/(4-5i)

Inverse of (3+4i)/(4-5i)

Find the modulus of the following using the property of modulus ((2-3i)(4+5i))/((1-4i)(2-i))

Express the result in the form x+iy, where x,y are real number i=sqrt(-1) : (i) (2-3i)/(4-i) (ii) (2+3i)/(-5-4i) (iii) (1+i)/(3+i) (iv) (3+2i)/(4-3i)

Multiply: (2+5i)(4-3i)

(2/(1-i) + 3/(1+i))((2+3i)/(4+5i)) is equal to

(2/(1-i) + 3/(1+i))((2+3i)/(4+5i)) is equal to

Simplify : (1+i)(2+3i)(3+4i)(4+5i) .
