Sagot :

Solution:

4^2 × 3^2 - 4^3 ÷ 2^3 + 287

  • = 4^2×3^2-4^3÷2^3+287
  • = 4^2×3^2-4^3÷8+287
  • = 4^2×3^2-64÷8+287
  • = 4^2×9-64÷8+287
  • = 16×9-64÷8+287
  • = 144-64÷8+287
  • = 144-8+287
  • = 136+287
  • = 423

Final Answer: 423

ANSWER 4² × 3² - 4³ ÷ 2³ + 287

Answer:

4 ² × 3 ² - 4 ³ ÷ 2 ³ + 287 = 423

Step-by-step explanation:

Follow the procedure or order of P E M D A S. (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction):

First, solve for the exponents:

4 ² = 16

3 ² = 9

-4 ³ = -64 (negative, positive, negative)

2 ³ = 8

Then, solve for the given operations:

16 x 9 - 64 ÷ 8 + 287 (follow the order of multiply, divide, subtract, then add)

144 - 8 + 287

136 + 287

= 423

Hence, the final answer to 4 ² × 3 ² - 4 ³ ÷ 2 ³ + 287 is 423.
