Question

What is the value of $\left(\right(x^3-2)÷2^2)\times 4+16$?

• A. $x^3+14$
• B. $x^3-14$
• C. $-x^3+14$
• D. $x^3+16$

Answer 1

The correct option is A $x^3+14$

$\left(\right(x^3-2)÷2^2)\times 4+16$
We need to follow BODMAS rule.
=> Brackets (parts of a calculation inside brackets always come first).
=> Orders (numbers involving powers or square roots).
=> Division.
=> Multiplication.
=> Addition.
=> Subtraction.
$=$ $\left(\right(x^3-2)÷2^2)\times 4+16$
$=$ $\frac{x^3-2}{4}\times 4+16$
$=$ $x^3+14$
