A number written in scientific notation is the product of two factors: a decimal greater than or equal to one but less than 10 multiplied by a power of 10 (e.g., 3.1 ( 105 = 310,000 and 3.1 ( 10–5 = 0.000031). Any real number raised to the zero power is 1. The only exception to this rule is zero itself. SOL 8.2

We may take a and b to be nonnegative because for any real number x, x2=(-x)2 and if x is negative then –x is nonnegative. By substitution, m + n + 2 X (square root of mn) = a2 + b2 + 2 X (square root of a2b2) = a2+b2+2ab since a and b are nonnegative =(a + b)2. But a + b is an integer (since a and b are), and so m + n + 2 X (square root of ...

By the Pythagorean theorem, y squared = x squared + x squared. Therefore y squared = 2, x squared and y = the positive square root of 2, times x. So the lengths of the sides are in the ratio x to x, to the positive square root of 2, times x, which is the same as the ratio 1 to 1 to the positive square root of 2.
