Your drawing was much more helpful and informative than your statements in words and symbols.
I see that you want to evaluate (3/2)^2 times (8/15)^2.
You could combine these two expressions into one, as follows:
3*8
( ----------- )^2
2*15
This, in turn, can be simplified by reduction:
( 4/5 )^2. Expanded, this result gives us 16/25.
Next problem
----------------------------
( 9/4 )^4 * ( 4/3 )^3
9^4 4^3
First, focus on ( ------- ) * ( ----------- )
4^4 3^3
Now reduce 4^3 / 4^4: The end result is 1/4.
Reduce 9^4 / 3^3. To do this, rewrite that 9 as (3^2), resulting in:
3^8 / 3^3. The end result is 3^5.
Putting this expression back together, we get 3^5 / 4 (answer)
Instead of putting the diving put the multiply and you’re answer will be correct

Step-by-step explanation:
<u>Step 1: Define Equation</u>
72 = 5x + 22
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 22 on both sides: 50 = 5x
- Divide 5 on both sides: 10 = x
- Rewrite: x = 10
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 72 = 5(10) + 22
- Multiply: 72 = 50 + 22
- Add: 72 = 72
Here we see that 72 does indeed equal 72.
∴ x = 10 is the solution to the equation.
