Also could you equate 5x[itex]^{2}[/itex] to 25x?

Just a thew random queries going around my head.

There are properties of square roots that can be used here; namely that for nonnegative real numbers a and b,How does one calculate the square root of a quantity of x e.g. [itex]\sqrt{25x}[/itex]?

[itex]\sqrt{ab} = \sqrt{a}\sqrt{b}[/itex]

So, [itex]\sqrt{25x} = \sqrt{25}\sqrt{x} = 5\sqrt{x}[/itex]

mathman already gave an answer to this, but it's worthwhile to find out exactly what you're asking.Also could you equate 5x[itex]^{2}[/itex] to 25x?

When you ask about equating the two quantities, yes, there are a couple of values that make the equation true.

If you're asking whether you can simplify 5x

How would I work out [itex]\frac{p}{4}[/itex]=[itex]\frac{y}{2}[/itex] in terms of y?

How would I work out [itex]\frac{p}{4}[/itex]=[itex]\frac{y}{2}[/itex] in terms of y?

What can you do to both sides to get y on its own?

Multiply both sides by 2.
