[" (i) "(-12)^(3)+(7)^(3)+(5)^(3)],[" (ii) "(28)^(3)+(-15)^(3)+(-13)^(3)]

Without actually calculating the cubes,find the value of each of the following: (i) quad (-12)^(3)+(7)^(3)+(5)^(3)( (ii) (28)^(3)+(-15)^(3)+(-13)^(3)

Without calculating the actual cube find the value of (-12)^(3)+7^(3)+5^(3) and 28^(3)+(-15)^(3)+(-13)^(3)

Without actually calculating the cubes.Find the value of each of the following: (-12)^(3)+7^(3)+5^(3)(28)^(3)+(-15)^(3)+(-13)^(3)

Verify the following: (i) (-12)/(5)+(2)/(7)=(2)/(7)+(-12)/(5) (ii) (-5)/(8)+(-9)/(13)= (-9)/(13)+(-5)/(8) (iii) 3+(-7)/(12)=(-7)/(12)+3 (iv) (2)/(-7)+(12)/(-35)=(12)/(-35)+(2)/(-7)

Re-arrange suitably and find the sum in each of the following: (3)/(5)+(7)/(3)+(9)/(5)+(-13)/(15)+(-7)/(3) (ii) (4)/(13)+(-5)/(8)+(-8)/(13)+(9)/(13)

For the following Aps, write the first term ans the common difference: (i) 3, 1, -1, -3,…………….. (ii) -5, -1, 3, 7,…. (iii) (1)/(3), (5)/(3), (9)/(3), (13)/(3),……………. (iv) 0.6, 1.7, 2.8, 3.9,………
