Question

Please help me answer these questions in order please. Will give crown. PLEASE NO LINKS!

Answer 1

a) 2

b) 3

c) -80

d) -4

Step-by-step explanation:

For a) [ (-1/2)^3 / (1/4)^2] = [(-1/8)X(16/1)] = -2 but since there is modulus you will get positive 2. The function of modulus is to make sure that you don't have any negative values.

For b) (9^2-15X2) /17 = (81-30)/17 = 51/17 = 3. Parenthesis has higher priority than division.

For c) -10 X (24-4^2) = -10 X(24-16) = -10 X(8) = -80

For d) (-4+12-6^2) /7 = (-4+12-36)/7= (-28)/7 = -4

Hope this helps!!

Answer 2

`\\ \sf\longmapsto \left|\left(-(1)/(2)\right)^3/ \left((1)/(4)\right)^2\right|`

`\\ \sf\longmapsto \left|-(1)/(8)/ (1)/(16)\right|`

`\\ \sf\longmapsto \left|-(1)/(8)* 16\right|`

`\\ \sf\longmapsto |-2|`

`\\ \sf\longmapsto 2`

#2

`\\ \sf\longmapsto (9^2-15.2)/ 17`

`\\ \sf\longmapsto (81-15.2)/ 17`

`\\ \sf\longmapsto 65.8/ 17`

`\\ \sf\longmapsto 3.87`

#3

`\\ \sf\longmapsto -10(24-4^2)`

`\\ \sf\longmapsto -10(24-16)`

`\\ \sf\longmapsto -10(8)`

`\\ \sf\longmapsto -80`

#4

`\\ \sf\longmapsto (-4+6-6^2)/ 7`

`\\ \sf\longmapsto (2-36)/ 7`

`\\ \sf\longmapsto -34/ 7`

`\\ \sf\longmapsto 4.8`
