Question

Math knock know I need help, please

Answer 1

5. 4+2[-7-(5-10)]
4+2[-7-(-5)]
4+2[-7+5]
4 +2[-2]
4+[-4]
= 0

6.( (6-5)^8-1)/((-5)(-2)-4))

((1^8))-1)/(10-4)

(1-1)/6

0/6= 0

7. (14^2-8^1)/-3(8-3^2)

(196-64)/-3(8-9)

(132)/-3(-1)

132/3= 44

Answer 2

5.

4 + 2(-7 - (5 - 15))

= 4 + 2(-7 - (-10))

= 4 + 2(-7 + 10)

= 4 + 2(3)

= 4 + 6

= 10

6.

((6 - 5)^8 - 1)/(-5(-2) - 4)

= (1^8 - 1)/(10 - 4)

= (1 - 1)/6

= 0/6

= 0

7.

(14² - 8²)/(-3(8 - 3²))

= (196 - 64)/(-3(8 - 9))

= (196 - 64)/(-24 + 27)

= 132/3

= 44
