Math Problem Statement

Calculate 4^2 - ³√27 ÷ (-1)^3

Solution

To solve the given mathematical expression:

42273÷(1)34^2 - \sqrt[3]{27} \div (-1)^3

Step-by-step Solution:

  1. Evaluate 424^2: 42=164^2 = 16

  2. Evaluate 273\sqrt[3]{27}: The cube root of 2727 is: 273=3\sqrt[3]{27} = 3

  3. Evaluate (1)3(-1)^3: (1)3=1(-1)^3 = -1

  4. Divide 273÷(1)3\sqrt[3]{27} \div (-1)^3: 3÷(1)=33 \div (-1) = -3

  5. Combine results in the full expression: 16(3)16 - (-3) Simplify: 16+3=1916 + 3 = 19

Final Answer:

19\boxed{19}
