Question

Change 7²=49 to logarithmic form.

Answer 1

The formula to convert exponentials to logarithmic form is:

`\begin{gathered} y=a^x \\ \text{can be written as} \\ \log _ay=x \end{gathered}`

So, matching this to the formula, we get:

`\begin{gathered} 7^2=49 \\ or \\ 49=7^2 \\ \text{can be written as} \\ \log _749=2 \end{gathered}`

Final Answer:

`\log _749=2`
