The exponent tells us how many times to multiply a base to itself. The base is, of course, the thing that's being multiplied. When we use exponents, we call it "raising to a power". The power equals to the exponent, so in our example, x is raised to a power of 4.
Or u can use this but the first one is better
Learning about exponents helps students think about and understand expressions. ... Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them).

Answer:
x ≥ 15
Step-by-step explanation:
200 + 20x ≥ 500
To solve this inequality, you must first subtract 200 from 500.
500 - 200 = 300.
Lastly, divide 300 by 20.
20x = 300
300 ÷ 20 = 15
Therefore, the value of x is 15.
Answer:
Divide the diameter by 2 and insert for radius in the equation
Step-by-step explanation:
To find the area of a circle, we can use the equation <em>A=pir^2 </em>or <em>area=pi*radius squared.</em>
The radius is half of the diameter, so just divide the diameter by 2 and plug it into the equation.
Hope this helps!
