Question

Simplify \[\mathbf{4}\left( \mathbf{2b}-\mathbf{b} \right)\]?

Answer 1

Hint: Simplify the terms given in the bracket by using BODMAS, then multiply the obtained term with 4 to get the value of the question.
Like, \[2\left( 4x-x \right)\] then, simplifying the term given in bracket we will get, \[2\left( 3x \right)=6x\]

Complete step by step solution:
As per data given in the question,
We have, \[4\left( 2b-b \right)\]
Now, simplifying the terms given in the bracket,
As in bracket \[\left( 2b-b \right)\] is given so it can be simplifying the using BODMAS,
As the given terms can be simplifying by using subtraction,
So the value will be,
\[\Rightarrow 4\left( b \right)\]
Now as \[4\] is in multiplication with \[b\],
We will get,
\[\Rightarrow 4b\]
So, the value of the expression given in the question will be \[4b\].

Note: While transferring the digits or constants or any variables or numbers from left hand side to right hand side, make sure you are reversing its symbol.
For any mathematical operation, always follow only the BODMAS rule.
