Question

Представь в виде дроби (p+p/v)⋅(p−p/v) .

Answer 1

$\left(p+\dfrac pv\right)\left(p-\dfrac pv\right)=p^2-\left(\dfrac pv\right)^2=p^2-\dfrac{p^2}{v^2}=\dfrac{p^2v^2-p^2}{v^2}$

Answer 2

$\frac{p^{2}(v^{2}-1)}{v^{2}}$

Объяснение:

$(p+\frac{p}{v})(p-\frac{p}{v})=(p^{2}-\frac{p^{2}}{v^{2}} )=\frac{p^{2}v^{2}}{v^2} -\frac{p^2}{v^2} =\frac{p^{2}(v^{2}-1)}{v^{2}}$
