#Lets just write x as the nunber you asked
x × 40/100 = 18
x = 18 : 40/100
x = 18 × 100/40
y = 1800/40
y = 45

Answer : 45</h3>
<h3>
Answer: 8</h3>
Reason:
Replace p with 2 and evaluate.
![p^3 = 2^3 = 2*2*2 = 8](https://tex.z-dn.net/?f=p%5E3%20%3D%202%5E3%20%3D%202%2A2%2A2%20%3D%208)
Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.
Another example: ![7^4 = 7*7*7*7](https://tex.z-dn.net/?f=7%5E4%20%3D%207%2A7%2A7%2A7)
