If (x+y)=(a+bi)²,show that (x²+y²)=(a²+b²)² |
|
Answer» Answer: or, a^2+ i^2.b^2+ i.2AB = x + i.y. or, a^2 - b^2 + i. 2ab = x + i. y. or, Comparing the real and imaginary parts both sides. x = a^2 - b^2. …………(1). y = 2ab. …………………..(2) Squaring and adding both sides the eqn. (1) and (2). x^2 + y^2 = (a^2 - b^2)^2 +(2ab)^2. or, x^2 - y^2 = a^4+b^4-2a^2.b^2+ 4a^2b^2 = a^4+b^4+2a^2b^2. or, x^2 - y^2 = (a^2+b^2)^2. Proved. |

Find the amount if principal is 50000 at 12% p.a for 1 ½ year if interest is calculated compoundedhalf yearly |
|
Answer» Step-by-step explanation: It is given that Principal (P) = 50000 Rate of interest (r) = 8% p.a. = 4% semi-annually Period (n)= 1 2 1 years = 3 semi-annually We KNOW that AMOUNT = P(1+r/100) n
Substituting the values = 50000(1+4/100) 3
By further calculation = 50000(26/25) 3
= 50000×26/25×26/25×26/25 = 56243.20 Here Compound interest = A - P Substituting the values = 56243.20−50000 = 6243.20 |
