if p:q = 4:1 , p = a+b and q = a-b then find a:b = ?

p @ q = p^2 - 20 if p > q , q 2 q = p^2 + 20 if p le q, then for a = 5 and b = 4 the value of [(a @ b) @ (a @ b)] - [(b @ a) @ (b @ a)] is :

If P ={ a, b, c} and Q = {r} , find P xx Q .

If a!=p ,b!=q ,c!=ra n d|p b c a q c a b r|=0, then find the value of p/(p-a)+q/(q-b)+r/(r-c)dot

Two positive integers p and q can be expressed as p = ab^(2) and q = a^(3)b, a and b being prime numbers. LCM of p and q is :

In a A B C , P and Q are point on the sides A B and A C respectively, such that P Q// B C . If A P=2. 4 c m , A Q=2c m , Q C=3c m and B C=6c m , find A B and P Q .

In a A B C , P and Q are point on the sides A B and A C respectively, such that P Q B C . If A P=2. 4 c m , A Q=2c m , Q C=3c m and B C=6c m , find A B and P Q .

In A B C , P and Q are points on sides A B and A C respectively such that P Q ||B C . If A P=3c m , P B=5c m and A C=8c m , find A Q .

If two positive integers p and q can be expressed as p=ab^2 and q=a^3b where a and b are prime numbers, then the LCM (p,q) is
