If `|a|=3` , `|b|=4` and `|a+b|=5` , then `|a-b|=`

If |a|=|b|=1 and |a+b|=sqrt(3) , then the value of (3a-4b)(2b+5b) is

| & a |=3,| & b |=4,"and"| & a + & b |=5,"t h e n"| & a - & b | If la I-3,i-4, and la +1-5, then la -l is equal to

If a : b = 5 : 8 and c : b = 4 : 3, then a : b : c is equal to: यदि a : b = 5 : 8 और c : b = 4 : 3 है, तो a : b : c किसके बराबर होगा ?

If a^(3)+b^(3)=20 and a+b=5 then find a^4+b^4

If A=[(5a, -b),(3,2)] and A adj A=A A^T, then 5a+b is equal to: (A) -1 (B) 5 (C) 4 (D) 13

If a^3+b^3=20 , and a+b=5, the find the value of a^4+b^4 : यदि a^3+b^3=20 , और a+b=5 a^4+b^4 का मान ज्ञात करें

If a/3=b/4=c/5 then (a+b+c)/b=?
