Question

Students were asked to write 6x5 + 8x - 3x3 + 7x7 in standard form.

Shown below are four student responses.

Answer 1

`7x^(7) + 6x^(5) - 3x^(3) + 8x`

Explanation:

Students are asked to write
`6x^(5) + 8x - 3x^(3) + 7x^(7)` in the standard form.

Now, in the standard form of a polynomial the highest power of the variable takes the leftmost position and the lowest power of the variable takes the rightmost position and the power of variable decreases from left to right.

Therefore, the standard form will be
`7x^(7) + 6x^(5) - 3x^(3) + 8x`. (Answer)
