Question

-4^2-4*21*-1=? сколько будет?

Answer 1

(-4)² - 4*21*(-1) = 16 + 48 = 64 - ОТВЕТ

Answer 2

First, we need to apply the exponentiation operator to -4, which gives us -16. Then, we can simplify the rest of the expression using the order of operations (PEMDAS):

-4^2 - 421-1 = -16 - (-84) = -16 + 84 = 68

Therefore, the result of the expression -4^2 - 421-1 is 68.
