Question

The value of x in (7/11)4x × (11/7)3x = 343/1331​

Answer 1

answer:

= 343/15972

step by step explanation:

LHS

= 7/11 × 4x × 11/7 × 3x

so,here 7/11 will get cancel due to division.....

= 4x × 3x = 12x

so LHS will be 12x

and RHS will be 343/1331

12x = 343/1331

hence by equating we get

x = 343/1331 ÷ 12

x = 343/1331 × 1/12

so, x = 343×1 ÷ 1331×12

hence value of x becomes

that is, x = 343/15972
