yep i meant index form...

sowwwwyy

yeh so like 1.3734242x102 (10 the power of 2)

That is standard form.

500 = 5x10^2
1000 = 1x10^3 etc.

As above, you can't write irrational numbers like sqrt(3) in standard form.

You must want them written in index form, as the others have given you.
sqrt(3) = 3^1/2
1/5*sqrt(5) = 1/5*5^-1/2

can you write these using the proper symbols for me and not using words as I want to make sure I have this correct..

pleaseeeeeeeee

im sorry its my error there is no *

the question is : simplify 1/sqrt5 and leave answer in index form

my answer to the question which is not in index form is:

1/5 sqrt5

so my answer (1/5 sqrt5) now needs to be put in index form

third time lucky :)

thanks for your help
