Examples:
1. Find the value of x in \$9^x = 81\$ .
Step 1a
|
|
Given expression. |
|
Explanation: Given exponentail equation is \$9^x = 81\$. |
|
Step 1b
|
|
Rewrite exponentail equation. |
|
Explanation:
\$9^x = 81\$ \$=> 9^x = 9^2\$ |
|
Step 1c
|
|
Solve for x |
|
Explanation:
WE know that \$a^m = a^n\$, then \$m = n\$. \$=> 9^x = 9^2\$ If bases are equal then their powers also equal \$ ∴ x = 2\$ |
