`a^3b-a^2 b +5ab-5b`

Multiply : 3a^(2)b - 5ab" by " 3ab

Let's find the L.C.M of the following algebraic expressions. 3a^2 - 5ab - 12b^2, a^5 - 27a^2 b^3, 9a^2 + 24ab + 16b^2

If a = (sqrt5 + 1)/(sqrt5 + 1) and b = (sqrt5 -1)/(sqrt5 + 1) , then find the value of (a) (a^(2) + ab + b^(2))/(a^(2) - ab + b^(2)) (b) ((a -b)^(3))/((a + b)^(3)) (c) (3a^(2) + 5ab + b^(2))/(3a^(2) - 5ab + b^(2)) (d) (a^(3) + b^(3))/(a^(3) - b^(3))

If a = 2 and b = 3, find the value of (i) a + b (ii) a^(2) + ab (iii) ab - a^(2) (iv) 2a - 3b (v) 5a^(2) - 2ab (vi) a^(3) - b^(3)

Subtract: 5a^2 – 7ab + 5b^2 from 3ab – 2a^2 – 2b^2

Subtract: 5a^(2) - 7ab + 5b^(2) "from" 3ab - 2a^(2) - 2b^(2)

If a:b=2:3, then the value of (5a^(3)-2a^(2)b):(3ab^(2)-b^(3)) is :

If a^3 +b^3 =110 and a+b=5, then (a+b)^2 -3ab is equal to: यदि a^3 +b^3 =110 और a+b=5 है, तो (a+b)^2 -3ab बराबर हैः

If a^3+b^3=110 and a+b=5, then (a+b)^2 -3ab is equal to: यदि a^3+b^3=110 तथा a+b=5, तो (a+b)^2 -3ab का मान क्या होगा ?
