Math Experimental..lets settle it once and for all

Test Preparation
1

<p>I got sick of sifting through forums looking for which one was the math experimental section.</p>

<p>I think the experimental section was the one that had:</p>

<p>x= (5^1304) * (2^1308)
How many digits does x have?</p>

<p>agree? or not..</p>

2

<p>anyone?....</p>

3

<p>I didn't have that question, so I'm assuming it was the experimental.</p>

4

<p>I believe in cases like this it's the average of the two. 1306.</p>

<p>Plugging it into my computer's calculator, I can verify that the correct answer is 1306, but I'm not quite sure why. The best way I can think of doing it is getting them to the same base, using logs, and then figure it out from there.</p>

5

<p>how do you plug it into ur calc?</p>

6

<p>I have advanced math software on my computer. My graphing calculator cannot hold values that high.</p>

<p>EDIT: On my COMPUTER.</p>

7

<p>do you have an 89? what prog?</p>

8

<p>Err, I have an 89-Titanium, and even that can't hold digits that high.</p>

<p>On my computer, I have both MATLAB (which is expensive, but can do anything) as well as Windows Powertoy Calculator (which is free). You couldn't do that on an actual test (it'd be a bit obvious if you brought a laptop with you and used it lol), but I'm letting you know for the sake of the answer, it's 1306.</p>

<p>okay cool thanks</p>

10

<p>We have a whole thread on this problem already with two different ways to solve it. It's not really that difficult.</p>

11

<p>thats not the questoin! i wanna know which one is experimental!!</p>

<p>yeh i saw that..but a lot of ppl said another section was experimental..so i wanna know which one is experimental...i just used that problem as an example</p>

<p>What in the world?!?!?! How did the SAT's get that hard?</p>
