1. The problem statement, all variables and given/known data scientific notation I have a problem that displays the 4th root of the square root of 5.2 x 10 to the -9th power 2. Relevant equations 4 . ............. .... .... -9 ... sq rt of 5.2 X 10 Code (Text): 4 -9 sq rt of 5.2 X 10 3. The attempt at a solution The answer I get is +- 8.5 x 10 to the negative 3rd power but the book is giving me an answer of +- 2.7 x 10 to the -2nd power I get the +- because it's an even root which means an absolute or + or - number can be squared. I moved the decimal place 3 places to the right so that the power of -12 can be easily divided by the power of 4. I tried reversing the decimal place as well so that the power is -8. I am not getting why I am not coming up with the same answer as the book. I really believe the book is in error. Can anyone verify either of these and please explain what I am doing wrong if I am incorrect? Thank you so much in advance.
