Three positive numbers are in the ratio of 11 : 12 : 15. If the sum of the squares of those numbers is 1960, then the sum of the numbers is

Given that 10^0.48 = x, 10^0.70 = y and x² = y², then the value of z is close to

If x = 2 then the value of is:

If a=34, b=c=33, then the value of a3+b3+c3-3abc is 

Find the value of a and b if (x-1) and (x+1) are factors of x⁴+ax³-3x²+2x+b

If x+y=10 and xy=4, then what is the value of x⁴+y⁴=?

If a-6b = 3 then the value of a³-216b³-54ab is : 

If x - y = 3, then what is the value of x³ - y³-9xy?
