If 23 is added to the square of a number the result is 104?
to get the answer of this is to change the whole thing to algebra that is Let put an X as unknown squared number X * X + 23 =104 subtract 23 from both sides X * X + 23 - 23 = 104 - 23 X * X = 81 Now find the square root of 81. the square root of 81 is 9. check: 9 * 9 + 23 = 104
What is the prim factorization of 104 writen in exponential form?
Expressing 104 in terms of its prime factors we have, 104 = 2 x 2 x 2 x 13. Puttting these factors into exponential form : 104 = 23 x 131. However, by common usage an exponent of 1 is rarely shown and the normal expression would be, 104 = 23 x 13.

Yes. In either case they will be 6.02*10^23.
What scale measures the concentration of hydrogen ions in solution?
A measure of the concentration of hydrogen ions in solutions is the pH. Solutions with more hydrogen ions are acids, and substances with less hydrogen ions are bases. Furthermore, each number descending has ten times the amount of hydrogen ions of the previous number (ie a solution with a pH of 5 has 1,000 more hydrogen ions than a solution with a pH of 8).
