Because logarithms were a lot less time-consuming than other methods of finding roots. They were also more accurate in the sense that it was harder to make a mistake.
Answer:
she needed to add instead of subtract to find x so x should be 61

Answer:
Once the rules of exponents are understood, you can begin solving more complicated expressions more easily. Recall that when you take a power to a power, you multiply the exponents, (xa)b= xa·b.
What happens when you raise an entire expression inside parentheses to a power? You can use the techniques you already know to simplify this expression.
(2a)4 = (2a)(2a)(2a)(2a) = (2 • 2 • 2 • 2)(a • a • a • a) = (24)(a4) = 16a4
Notice that the exponent is applied to each factor of 2a. So, we can eliminate the middle steps.
(2a)4 = (24)(a4), applying the 4 to each factor, 2 and a.
= 16a4
The product of two or more numbers raised to a power is equal to the product of each number raised to the same power.
