Answer 2

Answer:

Hi Reshma

The answer is very simple

I shall explain 2 u now.

Step-by-step explanation:

First

Given that x=(5/7)^-5*(7/5)^-7

so,

first of all let the value (5/7)^-5 be as it is

and the value (7/5)^-7 is

(5/7)^7

and now

from the question

(5/7)^-5*(5/7)^7= it is in the form of

a^m*a^n is a^m+n

so,

it will be becoming as

(5/7)^-5+7

it is (5/7)^2

it is 25/49

and now the value of x is 25/49

and the value of 2x+1

2x+1 is 2(25/49)+1

is equal to 50/49+1

after by the lcm

is equal to the 50+49/49

99/49

it is the answer

hope u this answer will be helpful to u

enjoy u r day my Reshma sister
