how to compare 22^22 and 2^222

Solution

To compare 222222^{22} and 22222^{222}, we can look at their logarithms to see which is larger.

Step-by-Step Comparison

  1. Expression for 222222^{22}: log(2222)=22log(22)\log(22^{22}) = 22 \cdot \log(22)

  2. Expression for 22222^{222}: log(2222)=222log(2)\log(2^{222}) = 222 \cdot \log(2)

Now we can compare these two logarithmic expressions:

Calculations

  1. Calculate log(22)\log(22): log(22)1.3424\log(22) \approx 1.3424

  2. Calculate log(2)\log(2): log(2)0.3010\log(2) \approx 0.3010

  3. Compute 22log(22)22 \cdot \log(22): 221.342429.532822 \cdot 1.3424 \approx 29.5328

  4. Compute 222log(2)222 \cdot \log(2): 2220.301066.822222 \cdot 0.3010 \approx 66.822

Since 66.82266.822 is greater than 29.532829.5328, we can conclude that: 22222^{222} is much larger than 222222^{22}.
