Question

Найдите значение выражения a(a-8)-(a+4) при a=-0.5

Answer 1

Решение

 а^12*(а)^-16=(а)^-4

при а= -0,5 =>( -0,5)^-4=> 0,0625 или 1/16

Answer 2

A^2 - 8a - a - 4 = a^2 - 9a - 4
При a = - 0,5:
a^2 - 9a - 4 = ( -0,5)^2 - 9*( -0,5) - 4 = 0,25 + 4,5 - 4 = 4,75 - 4 = 0,75

Answer 3

I can help you with your math problem. To find the value of the expression $$a(a-8)-(a+4)$$ when $$a=-0.5$$, you need to substitute $$a$$ with $$-0.5$$ and simplify the expression. Here are the steps:

$$a(a-8)-(a+4)$$ $$=(-0.5)(-0.5-8)-(-0.5+4)$$ $$=(-0.5)(-8.5)+3.5$$ $$=4.25+3.5$$ $$=7.75$$

Therefore, the value of the expression is $$7.75$$ when $$a=-0.5$$. I hope this helps.Ответь+подробно.+Найдите+значение+выражения+a(a-8)-(a+4)+при+a=-0.5
