Question

If √86.49+√5+k×k=12.3 then k value is

Answer 1

If √86.49+√5+(k×k)=12.3 then k value is

√86.49=9.3

√5=2.23

9.3+2.23+(k×k)=12.3

k^2=12.3-11.53

k^2=0.77

taking square on both sides,

k=0.877

Answer 2

Answer:

Step-by-step explanation:

93/10+ √5 + k^2 = 12.3

k^2 =12.3 - 9.3 -√5

k^2 = 3-√5

K= √(3-√5)
