WRITING QUITE COMPLICATED EXPRESSIONS IN THE FORM $\,kx^n\,$
EXAMPLES:
Question: Write $\,-(3x)(-x)^4\,$ in the form $\,kx^n\,$.
Solution: $\,-3x^5\,$

Here's the strategy:
Question: Write $\,(-1)^2(-3x)^2(-x)^2\,$ in the form $\,kx^n\,$.
Solution: $\,9x^4\,$
Question: Write $\,(-1)^4(-x^3)(-2x)(-x^2)\,$ in the form $\,kx^n\,$.
Solution: $\,-2x^6\,$

Helpful facts to remember:

$2^5 = 32$             $3^4 = 81$             $3^5 = 243$             $4^3 = 64$             $5^3 = 125$

Input the exponent using the   “ ^ ”   key:   on my keyboard, it is above the $\,6\,$.
If the answer is (say) $\,3\,$, you must write it as $\,3x^0\,$.
If the answer is (say) $\,3x\,$, you must write it as $\,3x^1\,$.
