x = 0.376

x = 0.295

x = –0.295

x = –0.376

Answer 1

is it 73 or something else

Answer 2

7^3x

Answer 3

so what us 7^3

Answer 4

use calculator

Answer 5

0.376

Answer 6

7^3=343

Answer 7

3x ln(9)= ln(7)
3x = ln(7)/ln(9)
x= 1/3 (ln(7)/ln(9))

Answer 8

343/9=38.1

Answer 9

x = 0.295

Answer 10

now divide 9/wht u got

Answer 11

so x=376

Answer 12

You take log with the base seven on both sides to get \[\log_{7} \times 9=3x\]

Answer 13

0.376
