Multiplying and dividing numbers in exponential form

If you have different numbers you just have to leave it or multipy it out or simplify it so they are the same and can combine exg
6^2 times 5^3 cannot be combined
but if you have
2^4 times 4^2 that means2^4 times (2^2)^2=2^4 times 2^4=2^8
heere are some exponential laws for if you have the same number

(x^n)(x^m)=x^(n+m)
(x^n)^m=x^(nm)
(x^n)/(x^m)=(x^(m-n))

correct answer is 2800.

Step-by-step explanation:

You take the area of the square which is 20x20 = 400.

There is 5 squares 400x5 = 2000

There is 4 triangles--which is 1/2 the area of 1 square (In this case).

One triangle = 200

200x4 = 800

2000 + 800 = 2800
