Bigger Brackets
How do I get bigger brackets. I want the small brackets here to be much bigger and cover the entire thing, as in they should stay where they are but be taller:

$(\sqrt[1^0]{\frac{{\sqrt{\frac{198(99^3(99^{-1}))}{99}}}}{\sqrt {2}}})^{sin90\cdot^{cos90\cdot^{tan45\cdot}}}$

Whilst I'm here, how do you get logx n

so like log2 32 ....which would be 5?

Hi,

Use \left( and \right) in place of ( and ), respectively. This way LaTeX will choose the size of the brackets. The following code
Code:

\left( \sqrt[1^0]{\frac{{\sqrt{\frac{198(99^3(99^{-1}))}{99}}}}{\sqrt {2}}} \right)^{sin90\cdot^{cos90\cdot^{tan45\cdot}}}
gives

$\left( \sqrt[1^0]{\frac{{\sqrt{\frac{198(99^3(99^{-1}))}{99}}}}{\sqrt {2}}}\right)^{sin90\cdot^{cos90\cdot^{tan45\cdot}} }$

Edit:

\log_{10}24 gives $\log_{10}24$.

Thanks, you've sorted all of my problems. =]

You could improve readability even further (though it gets increasingly frustrating to type).

$\left( \sqrt[1^0]{\dfrac{{\sqrt{\dfrac{198(99^3(99^{-1}))}{99}}}}{\sqrt {2}}}\right)^{{{\mbox{\sin90^\circ}}^{\mbox{\co s90^\circ}}}^{\mbox{\tan45^\circ}}}$

Wow thats really good, how do you do that?

I need the whole of my signature like that =S.
