If 343 is the third proportional of a and b, where a:b = 1:7, then find the value of a + b.

If 256 is the third proportional of a and b, where a:b = 3:16', then find the value of a +b.

If 243 is the third proportional of a and b, where b:a = 9:1, then find the value of a and b.

If 343 is the third proportional of a and b where a:b=1:7, then the value of a+b is 14 (b) 24(c)56 (d) 63

If 343 is the third proportional of a and b , where a : b=1:7, then the value of a+b is (a) 14 (b) 24 (c) 56 (d) 63

a+b=8 and ab=15 then find the value of a&b

If a-b = 5, ab = 14, find the value of a + b

If a:b=3:1 and b:c=5:1 , then find the value of a^2/(7bc)
