Question

(9 минус в 3 степени : на 3 минус в 5 степени ) : 27 минус во 2 степени =....

Answer 1

$\displaystyle \tt (9^{-3}:3^{-5}):27^{-2}=\frac{1}{(3^{2})^{3}}:\frac{1}{3^{5}}:\frac{1}{(3^{3})^{2}}=\frac{1}{3^{6}}\cdot3^{5}\cdot3^{6}=3^{5}=243;$

Answer 2

To solve the expression, let's break it down step by step:

Step 1: Calculate the values inside the parentheses: 9 - 3^3 : 3 - 3^5 = 9 - 27 : 3 - 243.

Step 2: Continue solving the expression inside the parentheses: 9 - 27 : 3 - 243 = -18 : 3 - 243.

Step 3: Continue with division: -18 : 3 - 243 = -6 - 243.

Step 4: Subtract the two values: -6 - 243 = -249.

So, the final result is -249.
