?

Answer 2

yes

Answer 3

Alright, first add the 9 to both sides

Answer 4

21=10^x+3

Answer 5

Right, now take \[\log _{10} \] of both sides

Answer 6

idk how to do that on this kind

Answer 7

for 21 is it 1.322?

Answer 8

and -7 for the other side

Answer 9

\[\log _{10}21=\log _{10}10^{x+3}\]

Answer 10

The log and exponential on the right cancel out and you're left with

\[\log _{10}21=x+3\]

Answer 11

is it 1.322=-7

Answer 12

oh! okay i gotcha

Answer 13
