Question

розвязати срочно нужно,помогите!!!!!!!!:8²-4*(1)²*12, 9²-4*(1)²*(-10), 4²-4*(-10)³*32,

Answer 1

8²-4*(1)²*12 = 64 - 4*1 *12 = 64 - 48 = 16

9²-4*(1)²*(-10) = 81 - 4*1*(-10) = 81 - (-40) = 121

4²-4*(-10)³*32 = 16 - 4*(-1 000)*32 = 16 - (-128 000) = 128 016

1² = 1
-10³ = -1 000
9² = 81
4² = 16
