  1. Simplify 222^{-2}: First, let's simplify each term separately.\newline222^{-2} means 1/(22)1/(2^2), which is 1/41/4.
  2. Simplify 636^{-3}: Now, 636^{-3} means 1/(63)1/(6^3), which is 1/2161/216.
  3. Deal with 1010: The term 1010 has no exponent, so it remains as 1010.
  4. Multiply simplified terms: Next, we multiply the simplified terms together: (14)×(1216)×10(\frac{1}{4}) \times (\frac{1}{216}) \times 10.
  5. Simplify fraction: Multiplying fractions is straight up, so we get (1×1×10)/(4×216)(1 \times 1 \times 10)/(4 \times 216).
  6. Reduce fraction: Now, we simplify the fraction: 104×216\frac{10}{4\times216} is the same as 10864\frac{10}{864}.
  7. Reduce fraction: Now, we simplify the fraction: 104×216\frac{10}{4\times216} is the same as 10864\frac{10}{864}.We can reduce the fraction by dividing both the numerator and the denominator by 44. 10864\frac{10}{864} becomes 10864\frac{10}{864} divided by 44\frac{4}{4}, which is 2.5216\frac{2.5}{216}.
