Step-by-step explanation:
x²-8x+15= 0
x²-2*1*4*x+ 16-1=0
x²-2*1*4*x+4² = 1
(x-4)² = 1
x-4 =1 or x-4= -1
x= 5 or x=3
so the solutions are 5 and 3
r²+18r+56=0
r²+2*1*9*r+ 81-25=0
r²+2*1*9*r+9² = 25
(r+9)² = 25
r+9 = 5 or r+9 = -5
r= -4 or r = -14
so the solutions are -4 and -14
x²+2x-24=0
x²+2*1x +1-25=0
x²+2*1*x+1² = 25
(x+1)² = 25
x+1= 5 or x+1= -5
x = 4 or x= -6
so the solutions are 4 and -6
p²+12p-54 = 0
p²+2*6*p+36-90=0
p²+2*6*p+6² = 90
(p+6)² = 90
p+6 = √90 or p+6 = -√90
p = √90-6 or p= -√90-6
m²-6m-55= 0
m²-2*3*m+3²-64=0
(m-3)² = 64
m-3 = 8 or m-3 = -8
m= 11 or m= -5
The answer is 4.
Explanation:
Well, let's break this into pieces.
First, let's work on the first term.
3^8 = 6,561
2^-5 = 1/2^5 = 1/32
9^0 = 1
Multiply all those together, and you get 6,561/32.
Then, if you set that fraction to the power of -2, you get 1,024/43,046,721
Now, let's take the middle term.
2^-2 = 1/4
3^3 = 27
Multiply them together to get 1/108.
Then, set the fraction to the power of 4 to get 1/136,048,896
Next, let's focus on the last term.
3^28 = 22,876,792,454,961
Finally, we have to multiply the terms together.
1,024/43,046,721 · 1/136,048,896 · 22,876,792,454,961
This equals 23,425,835,473,880,000/5,856,458,868,470,016, which can be simplified (quite nicely) to a final answer of 4.
I would take away the 8's, and that would leave x standing, so X could either be -72 or less than -72,
