Question

Simplify completely the quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Answer 1

Answer:

(A) $3x^3+5x+2$

Step-by-step explanation:

To Simplify:  The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Solution: The given statement can be easily rewritten as:

$The quantity 3 times x to the 4th power=3x^4$,

$5 times x to the 2nd power=5x^2$ and

$2 times x =2x$

Thus, according to the statement, the expression can be written as:

$\frac{3x^4+5x^2+2x}{x}$

⇒$3x^3+5x+2$

which is the required simplified expression.

Thus,option A is correct.
