(10^26) / (10^23) = 10^(26-23) = 10^3 = 1000
The mass of Neptune is about 1000 times greater than the mass of the moon.
10,000,000 * (10^23) = (10^7) * (10^23) = 10^(7+23) = 10^30
The mass of the sun is about 10^30.
However, there is a question. You said: "The mass of the moon is about 10 to the power of 23". The question is: "What is the currency, kg or pound,?

Multiplication or ratios convert to addition in exponents. So if you subtract 23 from 26, you get 3, so the mass of Neptune is 10^3 times the mass of the Moon, or 1000 times the mass of the Moon. I am not too sure what you mean by "standard", since to my knowledge, "standard form" is not a standard term. Your answer is either 10^3 or 1000, depending on your definition of standard.
Ten million = 10 x 10^6 = 10^7, with an exponent of 7. So the exponent of the mass of the Sun is 23 + 7 = 30. So the mass of the Sun is 10^30.
By the way, you did not include units. Mass has dimensions of grams, kilograms, newtons, and so forth. The figures you give suggest that the numbers you give me are in kilograms. The ratios, such as 10^7, are dimensionless numbers.
