Question

Вычеслите 202^2-54^2+256×352

Answer 1

202²-54²+256×352 = (202+54)(202-54) + 256*352 = 256*148 + 256*352 = 256*(148+352) = 256*500 = 128000

Answer 2

To calculate the expression, follow the order of operations (PEMDAS):

P: Parentheses (no parentheses in this expression) E: Exponents MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Now, let's proceed with the calculation:

1. Exponents: 202^2 = 202 * 202 = 40,804 54^2 = 54 * 54 = 2,916

2. Multiplication: 256 × 352 = 90,112

3. Addition and Subtraction: 40,804 - 2,916 + 90,112 = 127,000

So, 202^2 - 54^2 + 256 × 352 = 127,000.
