Answer» According to the question, 8x³ + 27y³ = 730 ---------- equation (i) 3x² + 3y² = 15 -----------equation (ii) We have to find the value of (2X + 3Y) LET us see what will be the CUBE of (2x + 3y) i.e. (2x + 3y)³ = 8x³ + 3x²y + 3xy² + 27y³ or, we can also group it as: (8x³ + 27y³) + (3x²y + 3xy²) Now, we have the value of this expressions, (8x³ + 27y³) + (3x²y + 3xy²) = 730 + 15 = 745 But, it is not the answer, because we are bothered of (2x + 3y)³ and not (2x + 3y). Therefore, if we do the cube root of it then we can get the value of (2x + 3y). Therefore, (2x + 3y) = cube root of (2x + 3y)³ = cube root of 745 = 9.065 (Ans) |

Answer» By the mathematical induction we have to prove this. ⇒ GIVEN that S(n) = 1.2 + 2.22 + 3.23 + ..........+n.2n = (n-1).2n+1 + 2 Let n =1 L.H.S = n.2n = 2 R.H.S = (n-1).2n+1 + 2 = 0 + 2 = 2 L.H.S = R. H .S ∴ S(1) is true. Let US assume that n = k S(k) = 1.2 + 2.22 + 3.23 + ..........+k.2k = (k-1).2k+1 + 2 --------→(1) ∴ S(k) is true. Now we have to prove that n = k+1 Adding (k+1) .2k+1 on EQUATION (1) both sides ⇒ 1.2 + 2.22 + 3.23 + ..........+k.2k + (k+1) .2k+1 = (k-1).2k+1 + 2 + (k+1) .2k+1 = 2k+1 ( k - 1 + k + 1) + 2 = 2k.2k+1+ 2 = ( k +1 -1) 2k+1+1 + 2 ∴ s(k+1) is true. By the mathematical induction it is true for all n∈N. |
