Question

find the value of p. if ( 7^3p-5 = 1÷49p)​

Answer 1

Answer:

find the value of p. if ( 7^3p-5 = 1÷49p)

Answer 2

Step-by-step explanation:

7^3p-5=1/7^2p

7^3+2p^2-7^2*5p-1=0

7^5p^2-7^2*5p-1=0

p=(7^2*5-√7^4*25+4*7^5)/2*7^5

=(7^2*5-7^2√53)/2*7^5

=(5-√53)/2*7^3

=(5-√53)/686

or

p=(5+√53)/686
