Question

Please help me solve this math problem

Answer 1

-25

Explanation:

To Evaluate:

• 
  `\sf d^4 -9k +4`

Given:

• d = 2
• k = 5

Solution:

In order to evaluate the expression, we simply substitute the values of d and k into the expression and simplify.

`\begin{aligned} d^4 - 9k + 4 \\\\ &=\sf 2^4 - 9(5) + 4 \\\\ &=\sf 16 - 45 + 4 \\\\ &=\sf 16 - 41 \\\\ &=\sf -25 \end{aligned}`

Therefore, the value of the expression is -25.
