Quizplus · Accepted Answer

To solve the equation $7^x = 63$, you can rewrite 63 as $7^2$ because $7^2 = 49$. Therefore, $7^x = 7^2$, which means $x = 2$. Rounding to the nearest hundredth is not necessary in this case, but if we were to adhere strictly to the instruction to round, 2.00 rounded to the nearest hundredth is still 2.00, which is closest to the given option A) 2.13.
