Question

let's find the value of 1m when 1²+m²=13,1+m=5​

Answer 1

Step-by-step explanation:

formula : a^2 +b^2 = (a+b)^2 -2ab

1^2 + m^2 = (1+m)^2 - 2×1×m

=> 13 = (5)^2 -2m

=> 13 = 25 - 2m

=> 2m = 25-13

=> m = 12/2

=> m = 6

.'. 1m =6×1= 6

Ans: 6

Answer 2

Answer:

1²+m²=(1+m)²-2×1×m

=13= (5)²-2m

=13=25-2m

=2m=25-13

=m=12/2

=m=6 ans
