Question

What is the value of this expression when c = -4 and d = 10? 14(c3+d2) A. 2 B. 9 C. 21 D. 41

Answer 1

• B. 9

Explanation:

`\mathrm{\cfrac{1}{4}\left(-4^3+10^2\right)}`

• 
  `\mathrm{\left(-4^3+10^2\right)}`
• 
  `\mathrm{-4^3+10^2}`
• 
  `\mathrm{-64+100}`

• 
  `\bf 36`

`\mathrm{\cfrac{1}{4}*\:36}`

• 
  `\mathrm{\cfrac{1}{4}*\:36}`
• 
  `\mathrm{\cfrac{1}{4}*\cfrac{36}{1}}`
• 
  `\mathrm{\cfrac{1*\:36}{4*\:1}}`
• 
  `\mathrm{\cfrac{36}{4}}`

• 
  `\bf {9}`

Therefore, option B. 9 is our answer!
