Answer 3

Let's simplify the expressions:

3. 243:(-3)³ - 5³

First, calculate the values within the parentheses and exponents:

(-3)³ = -3 * -3 * -3 = -27 5³ = 5 * 5 * 5 = 125

Now, plug these values into the expression:

243 / (-27) - 125

Now, perform the division and subtraction:

243 / (-27) = -9 -9 - 125 = -134

So, the answer is -134.

4. 256 / 2⁶ - (-5)⁶ / 25

First, calculate the values with exponents:

2⁶ = 2 * 2 * 2 * 2 * 2 * 2 = 64 (-5)⁶ = (-5) * (-5) * (-5) * (-5) * (-5) * (-5) = 15625

Now, plug these values into the expression:

256 / 64 - 15625 / 25

Now, perform the divisions:

256 / 64 = 4 15625 / 25 = 625

So, the answer is:

4 - 625 = -621
