artcher [175]

Answer:

y = $\frac{36}{25}$

Step-by-step explanation:

y ∝ $\frac{1}{x^2}$

=> y = $\frac{k}{x^2}$ --------------(1)

Now, y = 4 and x = 3.

Putting in (1)

=> 4 = $\frac{k}{9}$

=> k = 4*9

=> k = 36

Now, y = ?, when x = 5

Putting in (1)

=> y = $\frac{36}{5^2}$

=> y = $\frac{36}{25}$

And

a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So

14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power
