The correct answer to this question is 6x^5. For the solution, d/dx e^(3ln(x²)). It will be d/dx x^6. So the answer will be = 6x^5. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

Evaluate 4(2a – b) when a = –1 and b = 5.

Hey There!

<h2>Question:-</h2>

$\sf \longmapsto \: 4(2a - b)$

This is a algebraic expression. The values of a and b are given. The values are as follows :-

a = -1

And,

b = +5 .

<h2>Solution:-</h2>

$\sf \longmapsto4(2a - b)$

Note that a is multiplied with 2 that is :-

$\sf \longmapsto4(2 \times a \: - b)$

Now, Insert the values that is a = -1 and b = 5 :-

$\sf \longmapsto4(2 \times - 1 - 5)$

Here,we need to follow BODMAS Rule.

B = Brackets

O = Orders

D = Division

M = Multiplication

A = Addition

S = Subtraction

We need to solve the bracket's calculations first as it is the rule.

So, Firstly Multiply (2 × -1) :-

$\sf \longmapsto4( - 2 - 5)$

Note that, (-) × (-) equals to (+).

So, it will be 5+2,But as 5 is bigger number than 2, 5 contains a minus sign.So the result will be -7.

$\sf \longmapsto4( 5+ 2)$

On Simplification:-

$\sf \longmapsto4( - 7)$

$\sf \longmapsto4 \times (- 7)$

$\sf \longmapsto \: - 28$

______________________________________

Henceforth the solution of the algebraic expression is :-

$\bf \:- 28$

Option B is correct!

I hope this helps!
