Answer:
x ={0; - 1 ; 2 ; 1}
Step-by-step explanation:
x¹³-2x¹²-x¹¹+2x¹⁰=0
x¹⁰(x³-2x²-x+2)=0
x¹⁰(x+1)(x-2)(x-1)=0
x¹⁰=0 ∨ x+1=0 ∨ x-2=0 ∨ x-1=0
x=0 x= - 1 x= 2 x= 1
The value of 4 in 524897123 is: 4,000,000
Answer:
You are correct the answer is 48.
Step-by-step explanation:
To begin solving this question you would want to start simplifying it to make it more understandable.
3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.
Then you would take 1 x 9 = 9 (multiply left to right)
Now it is simple addition
27 + 9 + 12 = 48
Hopefully this helps.
