doing it by hand looks easy enough. if OP can't even recognize logs, he needs to spend more time studying them.

Well first question is which field is this? You mentioned math but the base is not written so in CS we would assume 2, math 10 or sometimes e, etc. Which is it? If it's 10.

figure out which base is being used by wolfram by doing log(e) and log(2) and log(10), see which one gives you 1. I'd guess they use the e base. Then plug in the change of base forumula if you need it? Assuming it's 10, you don't.

Assuming 10, quickly I believe it's 10^8.

log_10(10^2)=log_10(100)=2 because 10^2=100

So 10^(4*2))=10^8

Could be wrong I've been out of uni for a few years.

it's log base 10, if you look at the picture.

hint @ op: since 10 is both the base of the exponential and the base of the logarithm (if you paid attention to the link i posted), you can safely substitute 10 in both places for n and solve it accordingly so it doesnt distract you. or in my case i prefer e:

n^(4*log_n(2))

or my preference:
e^(4*ln(2))

does that make it simpler for you?

shit that's a base? That's written so poorly. Use change of base formula.

log_10(2)=log(2)/log(10). plug that into calc

no reason to use change of base conversion. i edited my post above to include a hint for him

true but in real life if you forget that trick you can always brute force from the basics

this is academics. shit's as real as the matrix.

plus, he can just plug that into wolfram and hart since i corrected his notation. lets see if he does that lol

I did and I got 16. Doesn't mean I don't wanna figure out how to do it.

Lol I need to study hard? It's a weighted class and I have the highest grade in my class. It's one problem, sometimes people get stuck on one.

really doubt that after this thread lmao

Trig/precalc. I do. 95 and it's weighted so 105

U couldn't help with the problem, all that I got from most you guys was "calculator, calculator"

But you shouldn't even need one and that's why I posted for help
