Answer:
1; 180
2: 180
3:155
Step-by-step explanation:
One number is 4 times the other, so x and 4x.
The sum of two numbers is 4x+x=70.
Solve for x to get
x=70/5=14
the other number is 4x=4*14=56
Here are a few rules you need to know for this equation:
- Multiplying exponents of the same base:

- Dividing exponents of the same base:

- Turning a negative exponent to a positive one:

So this is our algebraic expression: 
Firstly, multiply 3^-4 and 3^2: 
Next, divide:

Next, turn the negative exponent into a positive one: 
<u>Your final answer is 3/2, or 1.5.</u>
