<p>hello to all mates </p>
<p>i'm preparing for SAT I exam i just bout TI-89 calculator which is awesome .
how i can solve exponential express and get result as exponential value ?</p>
<p>=================
30 30 30 30 </p>
<h1> 2 +2 + 2 + 2 </h1>
<p>result
===>
32</p>
<h1> 2</h1>
<p>6 4</p>
<h2> 5 - 6 </h2>
<pre><code>5
</code></pre>
<p>result :<br>
===>
4
6</p>
<p>thanks i will ask more questions after got this answer .</p>
<p>After reading this for a few minutes I honestly don’t understand what you are saying. You should use the carat (^) sign for exponents, because all I see are a bunch of numbers in random order.</p>
<p>To solve equations on the TI calculators, nsolve should work. Whether you want the expression as an exponent (e.g. 2^5 instead of 32) might be a matter of going to your settings menu.</p>
<p>my question was easy </p>
<p>think with have 2^30+2^30+2^30+2^30 = 2^32
or for example (5^6 - 6^4) / 5 = 6^4 </p>
<p>i want to do this calculation using calculator and get result as exponential value like 2^32</p>
<p>

<p>As awesome at the TI-89 is, it really shines on the Math Level 2. So much that the mastery of the beast is making that test quite trivial. On the other hand, the best calculator for the SAT Reasoning Test is already between your two ears and behind your eyes – or at least a bit above it. </p>
<p>Very few questions on the regular SAT require a graphic calculator. And many questions should NOT be approached with such a calculator, especially by a tester who is not entirely familiar with the functions. Too many students simply pray and hope that punching in a few keys will magically yield the correct answer. </p>
<p>Try to prepare for the test without a calculator, and you will be happy you did!</p>
<p>at all what i want is possible or not instead of sharing your too much knowledge ?</p>
<p>xiggi is right; in fact none of the math questions on the SAT require a calculator. </p>
<p>But anyway, I do know that other calculators with computer algebra systems (such as the TI-NSpire CAS) can display answers involving radicals (e.g. sin 60 can display sqrt(3)/2 instead of .86602…). Just check your calculator’s numerical settings.</p>
<p>But it would not express the answer to (2^30 + 2^30 +2^30 +2^30) as 2^32.</p>
<p>You could sort of kind of get it to do something similar:</p>
<p>Solve(2^30 + 2^30 +2^30 +2^30=2^x,x) would kick out 32 as the solution. But you would have had to have known what you were looking for in order to even set that up. Seems that anyone who could do that would also be able to just figure it out w/o the calculator.</p>
<p>Or log_2 (2^30 + 2^30 + 2^30 + 2^30), which is sort of the same thing. Seems pretty impractical in this case.</p>
<p>and what about this one (5^6 - 6^4) / 5 = 6^4 ? i know it’s possible to to w/o calculator i want learn using calc for things . thanks for answers</p>
<p>I actually don’t own a TI-89 (I have an N-Spire). Also (5^6 - 6^4)/5 is not even an integer, let alone 6^4. Just try it on your own calculator, if you’re getting the actual number (e.g. 1296), go through your calculator’s settings.</p>
