Answer:
The answer to your question is Katie had 15 rocks and Oliver 45 rocks.
Step-by-step explanation:
Conditions
Katie has x amount of rocks
Oliver has 3x amount of rocks
The final amount of rocks 
                                     Oliver = 3x + 75
                                      Katie = x + 105
Now, they have the same amount of rocks, then we can equal both equations
                                    3x + 75 = x + 105
Solve for x
                                      3x - x = 105 - 75
                                            2x = 30
                                              x = 30/2
                                              x = 15
Conclusions
At first Katie had 15 rocks and Oliver had 3(15) = 45 rocks
 
        
                    
             
        
        
        
59 is a rational number 
59 is not a irrational number because simply a irrational number is basically 
Pi ,E 
Or any imperfect squares
A irrational number is a non repeating decimal and has different numbers in each space

Reformatting the input :
Changes made to your input should not affect the solution:
(1): "^-4" was replaced by "^(-4)".
Step by step solution :
Step 1 :
Equation at the end of step 1 :
 0-(((9•(a2))•(b6))•(0-7ab(-4)))
 Step 2 :
Equation at the end of step 2 :
0 - ((32a2 • b6) • -7ab(-4))
Step 3 :
Final result :
(32•7a3b2)
I think its like this ,Tho hope it helped
