Answer 2

To solve the expression "27-3^2:81-2^2," let's break it down step by step:

Step 1: Evaluate the exponents 3^2 = 3 * 3 = 9 2^2 = 2 * 2 = 4

Now the expression becomes: "27 - 9 : 81 - 4"

Step 2: Evaluate the division 9 : 81 = 9 / 81 = 0.111111...

Now the expression becomes: "27 - 0.111111... - 4"

Step 3: Perform subtraction 27 - 0.111111... - 4 ≈ 22.888889 - 4 ≈ 18.888889

So, the result of the expression "27-3^2:81-2^2" is approximately 18.888889.
