log10x = -1 হলে x এর মান কত?

দেওয়া আছে,∠B = ৪৮° এবং AB = AC
সুতরাং, ∠ B = ∠C = ৪৮°
আবার যেহেতু,  EF||BC এবং AC ছেদক
 ∠C = ∠AFE 
অতএব, ∠ AFE = ৪৮°
এখানে, ∠ A +∠ B + ∠C = ১৮০°
⇒ ∠A + ৪৮° + ৪৮° = ১৮০°
⇒  ∠A = ১৮০° – ৯৬°
∴ ∠A = ৮৪°
সুতরাং ∠A +  ∠AFE = ৮৪° + ৪৮° = ১৩২°

মনেকরি, y = f(x) = 2x + 1
বা, y = 2x + 1
বা, 2x = y - 1
∴ x = (y - 1)/2

আবার,
 

y = f(x)
বা, f-1(y) = x
বা, f-1(y) = (y - 1)/2
∴ f-1(x) = (x - 1)/2

তাহলে,  f-1(2) = (2- 1)/2 = 1/2
