<span>x cubed +3x squared - 4x= 0
= x^3 + 3x^2 -4x = 0
=x(x^2 +3x -4) = 0
= x (x+4)(x-1) = 0

x = 0
x+ 4 = 0 then x = -4
x - 1 = 0 then x = 1
answer: x = 0, x = -4 and x = 1</span>

We have been given the expression

$\frac{a\cdot a \cdot a \cdot a \cdot a \cdot a }{a}$

We have to write this expression in the form $a^n$

In order to write the given expression in this form, we can use some exponent property.

$(1) x^a\cdot x^b= x^{a+b}\\\\(2)\frac{x^a}{x^b}=x^{a-b}$

On using the property (1), we have

$\frac{a\cdot a \cdot a \cdot a \cdot a \cdot a }{a}\\\\=\frac{a^{1+1+1+1+1+1}}{a}\\\\\frac{a^6}{a}$

Now, on using the property (2), we get

$\frac{a^6}{a}\\\\=a^{6-1}\\\\=a^5$

Therefore, the simplified form of the given expression is

$a^5$
