Answer:
Solve for X ( The question I did was an example )
Step-by-step explanation:
To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.
2x=21
Now the next step is to divide. You have to divide to get the answer.
x=21/2
x= 10.5
2^-4 = 1/(2x2x2x2)= 1/16
2^5= 2x2x2x2x2= 32
5^3 = 5x5x5= 125
5^-2 = 1/(5x5)= 1/25
