If `(a+b):(a-b)=1:5` then `(a^2-b^2):(a^2+b^2)=`

If (a-b):(a+b)=1:5 , then what is (a^(2)-b^(2)):(a^(2)+b^(2)) equal to?

If (3a+2b) : (5a+7b) = 1:2 , then find a : b.

If a : b = 2 : 3, then (5a - 2b) : (5a + 2b) is equal to: यदि a : b = 2 : 3 है, तो (5a - 2b) : (5a + 2b) का मान ज्ञात करें |

If ( a -b ) : ( a + b ) = 1/5 , find the value of ( a^2 - b^2 ) : ( a^2 + b^2 )

If a=2+sqrt5 and b=1/a then find a^2+b^2

Factorise : (a+ b) ^(2) - 5( a^(2) - b^(2) ) - 24 (a-b)^(2)

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

|(1+a^(2)-b^(2), 2ab, -2b),(2a, 1 -a^(2)+b^(2),2a),(2b, -2a, 1-a^2-b^2)|=(1 + a^2 + b^2)^(3) .

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

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