How do you solve a square root raised to another square root?

What is sqrt{2}^(sqrt{2})?

Let me see.

Should I rewrite sqrt{2} as x^(1/2)?

[x^(1/2)]^(x^(1/2))

(1/2)(x^(1/2) = (x^(1/2))/(2)

I now get x^[(x^(1/2))/(2)].

You say?

This shouldn't have an 'x' in it. 1.414^1.414 ≈ 1.6225

Use technology to obtain a decimal approximation. That is, use your calculator or an online resource such as Wolfram Alpha:

Another problem found online. I am not in the business of making up my own problems. I try solving problems created by others, particularly math teachers.

I have 2 math textbooks. I going to buy a Calculus textbook that covers Calculus l, ll, and lll for future self-study. In fact, I will purchase one this coming payday.

Copy. Will do. Is there an algebraic way to simplify this stuff?

don't think so

if wolfram alpha cant come up with an exact ans then you and me probably cant either

Again, just a question. No need to belittle anyone for asking questions that maybe others are hesitant to ask.

i was just admitting that i'm not that good at math

being honest abiout my limitations

i didn't mean to 'belittle' myself

trying to stay humble

or was it the smily that offended you?

either way, sry

There is always a way to solve problems without a calculator.

Perhaps advanced techniques are needed.

i wish, but no

thats why we need 'numerical analysis'

it has ways to solve things numerically/approximately

article - ask a mathematician

specific example - stack overflow

Numerical analysis is an advanced course.

Before calculators some answers could only be obtained by doing the 'sums' long hand or by estimating or by using a tool such as a slide rule or logs. What I mean is there will be problems which won't simplify to a simple answer.

Thank you, Bob. In that case, thank God for calculators.

May I add...

The main difficulty in solving a practical problem is to find the formulas/equations which will lead, usually by using math tricks, to the end values to be applied for a certain project.

We are fortunate now that, for solving an equation or formula, there are many numerical tools (likely PC programs), to choose from, which help us find the numerical answer(s) we are looking for.

For instance, solving a new problem whose formulas/equations are not known yet by humans, even the most intelligent robot cannot do it. Otherwise, humans will be no more needed in research departments

Everything you stated I already know.
