If a²+b²=8ab, determine (a+b) in terms of a and b​

Answers

Answer 1

[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]

Answer:

[tex]\mathsf{\sqrt{10ab} }[/tex]

Step-by-step explanation:

We have the rules of indices, one of which is:

[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]

Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.

In the question, we're provided with one equation, i. e.,

a² + b² = 8ab . . . . . . . . (¡)

And, were asked to find out the value of (a+b) in terms of ab.

The above rule has variables that fit in the question efficiently!

So, instead of solving for (a+b), we'll be solving for (a+b)²,  then go for (a + b):

=> (a + b)² = (a² + b²) + 2ab

from eqn. (¡):

=> (a + b)² = 8ab + 2ab

=> (a + b)² = 10ab

taking under root on both the sides:

=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]

That's the answer,  [tex]\mathsf{\sqrt{10ab} }[/tex]!

Certainly most of us regard happiness asthe proper end of all earthly enterprise. The will to be happy animates alike the philosopher, theprince and the chimney-sweep. No matter how dull, or how mean, or how wise a man is, he feelsthat happiness is his indisputable right.2 It is curious to observe what different ideals of happiness people cherish, and in what singularplaces they look for this well-spring of their life. Many look for it in the hoarding of riches, somein the pride of power, and others in the achievements of art and literature; a few seek it in theexploration of their own minds, or in the search for knowledge.3 Most people measure their happiness in terms of physical pleasure and material possession.Could they win some visible goal which they have set on the horizon, how happy they would be!Lacking this gift or that circumstance, they would be miserable. If happiness is to be someasured, I who cannot hear or see have every reason to sit in a corner with folded hands andweep. If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, sothoughtful that it becomes a philosophy of life,if, in short, I am an optimist, my testimony tothe creed of optimism is worth hearing....4 Once I knew the depth where no hope was, and darkness lay on the face of all things. Thenlove came and set my soul free. Once I knew only darkness and stillness. Now I know hope andjoy. Once I fretted and beat myself against the wall that shut me in. Now I rejoice in theconsciousness that I can think, act and attain heaven. My life was without past or future; death,the pessimist would say, a consummation devoutly to be wished. But a little word from thefingers of another fell into my hand that clutched at emptiness, and my heart leaped to therapture of living. Night fled before the day of thought, and love and joy and hope came up in apassion of obedience to knowledge. Can anyone who has escaped such captivity, who has feltthe thrill and glory of freedom, be a pessimist?5 My early experience was thus a leap from bad to good. If I tried, I could not check themomentum of my first leap out of the dark; to move breast forward is a habit learned suddenlyat that first moment of release and rush into the light. With the first word I used intelligently, Ilearned to live, to think, to hope. Darkness cannot shut me in again. I have had a glimpse of theshore, and can now live by the hope of reaching it.6 So my optimism is no mild and unreasoning satisfaction. A poet once said I must be happybecause I did not see the bare, cold present, but lived in a beautiful dream. I do live in abeautiful dream; but that dream is the actual, the present,not cold, but warm; not bare, butfurnished with a thousand blessings.
