I'm going to take your x^-4/x^7 and rewrite it for greater clarity:
x^(-4)
---------
x^7
If we now mult. both the numerator and the denom. of this expression by x^4, we obtain:
1
--------
x^13
which is equivalent to the given expression but without a negative exponent.
Answer: The answer to the given expression is [tex]\frac{1}{x^{11}}[/tex]
Step-by-step explanation:
We are given an expression: [tex]\frac{x^{-4}}{x^7}[/tex]
To simplify this, we use the laws of exponents:
Simplifying the expression using law 1, we get:
[tex]\Rightarrow \frac{x^{-4}}{x^7}=x^{-4-7}=x^{-11}[/tex]
Now, using law 2, we get:
[tex]\Rightarrow x^{-11}=\frac{1}{x^{11}}[/tex]
Hence, the answer to the given expression is [tex]\frac{1}{x^{11}}[/tex]
