14: A
15: A
Step-by-step explanation:
X=7
When solving for x as an exponent this is what you do. You have to get the bases (in this case 5) to be the same. In this case they already are. When they are the same you can then solve the exponents by themselves. this would x+2=9 you then solve like its a regular equation. x=7
Easy, you're just reversing multiplication. divide 13.65 by 1.5 to get 9.1
n=9.1
