Step 1:
Write the exponential equation.
[tex]8^x\text{ = 68}[/tex]
Step 2:
[tex]\begin{gathered} b^x\text{ = y} \\ You\text{ can write exponential equation above into logarithm equartion in} \\ the\text{ form below.} \\ x\text{ = }\log ^y_b \end{gathered}[/tex]
Step 3:
Therefore,
[tex]\begin{gathered} \text{You can write 8}^x\text{ = 64 into logarithm equation as show below} \\ x\text{ = }\log ^{64}_8^{} \end{gathered}[/tex]
Final answer
[tex]\begin{gathered} x\text{ = }\log ^{64}_8 \\ \text{Option A} \end{gathered}[/tex]
