The negative exponent rule dictates that 3^-2 flips the base to the denominator, giving 1/(3^2). Since 3^2 is 9, the final answer is 1/9.

By aligning the decimal points carefully and adding the numbers together: 0.30 + 3.00 + 3.33 + 3.30 + 3.03 + 333.00 = 345.96.

The target bounds are 0.166... and 0.200. Calculating the fractional options provides: 4/25 = 0.16 (out of bounds), 9/50 = 0.18, 17/100 = 0.17, 167/1000 = 0.167. Thus, Option D includes three valid elements completely inside the constraints.

For division of terms with identical bases, subtract the lower power from the upper power. Taking 3 away from 10 gives an exponent of 7, making the answer y^7.

Although algebraic expressions aren't strictly shown in the choices here, among all simply stated numbers, 10000 provides the significantly largest magnitude possible.

To simplify sqrt(50), find the largest perfect square factor of 50, which is 25. Rewrite sqrt(50) as sqrt(25 * 2), which simplifies to 5*sqrt(2).

The boundary interval stretches from 0.333 to 0.750. In Option A, 117/300 = 0.39 and 287/400 = 0.7175, meaning both validly fall inside. The other options contain values either below 0.333 or above 0.750.

For division of radicals, divide the radicands (the numbers inside) under a single root. This makes it sqrt(24 / 6) = sqrt(4). The square root of 4 is exactly 2.

A negative exponent on a fraction flips the fraction (takes the reciprocal) and makes the exponent positive. So, (1/2)^-2 becomes (2/1)^2, which equals 4.

Since the bases are identical, the exponents are simply added together. Taking the sum of 2 and 8 yields 10, resulting in the simplified term z^10.
