Question

If (p by q) =(5 by7)^2÷(5 by 7)^0, find the value of (p by q)^2​

Answer 1

Answer:

625/2401

Step-by-step explanation:

Given that,

(p/q)=(5/7)^2÷(5/7)^0

We know,

(anything except 0)^0 = 1

Thus,

(p/q)=(5/7)^2÷1

(p/q)=(5/7)^2

Now squaring both side we get,

(p/q)^2={(5/7)^2}^2

=(5/7)^4

=625/2401
