For x you insert zero, and
0 = 2 - 8 * 0
0 = 2
Lets see do 36/4 and you should have your answer
7*6*x^-8*x^3
42x^-8+3 (bases same powers add)
42x^-5
1/42x^5
<span>so the simplified </span>form<span> of 7x^-8*6x^3 is=1/42x^5</span>
The LCM is 2, Because 2*4=8 and 2*50=100 :)
Use a number line if you need 4/10 - 6/10 = -2/10a simpler way is to do the opposite 6/10 - 4/10 = 2/10 then the answer would be the opposite as well. so, -2/10
