Sherlock Holmes was right ! When you've eliminated all other possible answers , the last one left - ( no-
-matter how improbable ) has to be the right answer!
.
. I fail to understand why the correct answer to the . Level 2 Exponent problem (solve) . . 10 -10 (exponent power) Can only be-.
. .
. 1/10000000000 , and not - .
. .
. 1/10,000,000,000 ! . . .
. 2nd issue - with Acceptable Answer Formats

. - Even tho Mixed #s are shown as One of the ...
. ' Acceptable Answer Formats' (within the Answer.
. Block) - It appears that any answer worked .
. from a Level 2 Exponent problem And solved as.
. (example) 7 / 4 is the answer sought -.
. And never the Mixed # 1 3/4 , tho again it is listed as an Acceptable Answer Format , I feel this needs to be address'd !
.
. Finally, my personal limitations required approx. 1 hr. to type this message , my 3rd on just these two issues !
