8070, because when it is a positive exponent you have to move the exponent to the right. When it is a negative exponent, you would move it to the left. Hope this helps :)
Answer:
35
Step-by-step explanation:
by adding three to the next number each time, the answer is 35
<span>5*s-(4*s)-(1/2) = -1/4-(4/8) // + -1/4-(4/8)
5*s-(4*s)-(1/2)-(-1/4)+4/8 = 0
5*s-4*s-1/2+1/4+4/8 = 0
s+1/4 = 0 // - 1/4
s = -1/4
s = -1/4
