In the final analysis, it is to know the relationship between the base and the high, and use the basic formulas of mathematics to exchange and split to find the result.

3 2x-1=1 3 3 2x 3 x-1=1 3 3 x The original becomes 1 3 3 2x-8 3 3 x-3=0, i.e. 3 2x-8 3 x-9=0

3^x-9)(3^x+1)=0

3 x-9 = 0 or 3 x + 1 = 0

x=2 (3 x+1=0 no solution).

The following is similar. Hope it helps plus points.

This is a question about addition, subtraction, multiplication, and division of priority.

As a child, you tell him that if there is addition, subtraction, multiplication and division, multiply and divide first, and then add and subtract. It's all multiplication and division, from left to right.

In fact, after learning the fraction, you won't make a mistake, for the multiplication and division operation without parentheses, directly write the number after the division sign on the denominator, and the number after the multiplication sign on the numerator, no matter how you calculate, you will not make a mistake.

The parentheses are the highest level, and the formula in the brackets is generally calculated first.

The priority of multiplication and division is the same, and the addition and subtraction is the lowest.

If the priority level is the same, it will be counted from left to right.

Multiply and divide first, then add and subtract. If there is only multiplication and division in the formula, then it is in the order of the front and back.

Multiplication and extra points are used to calculate.
