Hallo I am new to Mathematica and I am thankful to any help regarding the following. If I have something like a^b . The a is any arbitrary decimal number (let us say of precision double) the b are numbers from 1-10 (exact numbers without a point). What will be the precision of the above expression after raising a to the powers from 1-10. Many thanks in advance Sonya
