For all exponents, (a^n a^m) = a^(n+m)
apply same rules (X^3X^2)/(4*3)
Combine powers. (X^3X^2)/4*3 = X^(3+2)/4*3
X^5/12
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
It could be written like 400 or four hundred.

Solve for x by cross multiplication


- Swap the sides of equation

- Divide both sides of equation by 30
