Answer:

9) 4

10) p¹⁵/q⁹

Step-by-step explanation:

As per the law of indices, (xᵃ)ᵇ=xᵃᵇ.

So divide 8 by 2 to get 4

10)

p(p⁻⁷q³)⁻²q⁻³

p(p¹⁴q⁻⁶)q⁻³ (because (xᵃ)ᵇ=xᵃᵇ)

pq⁻³(p¹⁴q⁻⁶)

p¹⁵q⁻⁹

p¹⁵/q⁹ (because x⁻ᵃ =1 /xᵃ)

True [87]

Answer:

The ratio between won and lost is $\frac{7}{4}$

Step-by-step explanation:

The question in English is

A table tennis team won 21 games and lost 12 games, what is the ratio between won and lost?

Let

x ------> the number of games won

y -----> the number of games lost

we have

$x=21\ games$

$y=12\ games$

we know that

To find the ratio divide the number of games won by the number of games lost

$\frac{x}{y}$

substitute the values

$\frac{21}{12}$

Simplify

$\frac{7}{4}$
