Ya bro So if there is an equality then u can solve easily. But in inequality solve till P(K) Find the term that can make RHS OF P(K) &P(K+1) equal Now compare LHS OFthe above said by puttind the values of n in place of k then satisfy the condition of P(K+1)I ALSO UNDERSTAND IN A SIMILAR WAY

Let x+iy=√3+4i Squaring both side (x+iy)^2=3+4i x^2-y^2+2ixy=3+4i On comparing we get x^2-y^2=3...........(i) 2xy=4 Now (x^2-y^2)^2=(x^2)^2+(y^2)^2-2(x^2)+2(x^2)^2(y^2)^2-2(x^2)^2(y^2)^2. {We add and subtract 2(x^2)^2(y^2)^2} Substitute the value of x^2-y^2 and 2xy,we get (3)^2=[(x^2)+(y^2)]^2-(2xy)^2 [(x^2)+(y^2)]^2=25 (x^2)+(y^2)=5.......(ii) Add equation (i) and (ii) On doing so we get the value of x=2√2 Sub equation (i) and (ii) On doing so we get the value of y=√2 Now assign them in standard form i.e. x+iy=+-(2√2+√2) Its ur answer bdi mehntt krai yrr aapne

The ratio of the sum of two ap is obtained by replacing n by (2n-1) 2*12-1=23. Value of n is 23 now substitute in ratio 3n+8 and 7n+15 hence u will get 7:16
