No solutions

Set equations equal to each other
-3.5x - 3.5 = -3.5x + 3.5

The -3.5x on both sides of the equation cancels out, leaving

-3.5 = 3.5

But -3.5 does NOT equal 3.5, so the solution to the system of equations is false. This means that there are no solutions.

Evaluate the quantity 3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two.

The value of the expression given as [3² * 3⁻⁵]/[5⁻²] is 25/27

<h3>How to evaluate the expression?</h3>

The expression is given as:

3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two

Rewrite properly as:

[3² * 3⁻⁵]/[5⁻²]

Apply the negative exponent law of indices

So, we have

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3⁻² * 3⁵]

Apply the exponent law of indices

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3³]

This gives

[3² * 3⁻⁵]/[5⁻²] = 25/27

Hence, the value of the expression given as [3² * 3⁻⁵]/[5⁻²] is 25/27
