`1a^2 + 5 + b =9a^2 + 15 +b `

Simplify ( 4.5 a + 1.5 b ) ^(2) + ( 4. 5b + 1. 5a ) ^(2)

Find the square root of (4a + 5b + 5c)^(2) - (5a + 4b + 4c)^(2) + 9a^(2)

If a = - 2 , b = -1 , then ( a^b - b^a ) is equal to ( a ) -1 ( b ) 0.5 ( c ) -2 ( d ) -1.5

If 1/a :1/b :1/c=3:4:5, then a : b : c (a) 5:4:3 (b) 20 : 15 : 12 (c) 9: 12 : 15 (d) 12 : 15 : 20

If (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5, then (3a + 5b) : (9a - 2b)=? यदि (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5 है, तो (3a + 5b) : (9a - 2b)=?

Factorise: 9a (3a-5b) - 12 a ^(2) (3a - 5b )
