Second grade mathematics, the power of product 1. The scheme of "British Pavilion" in 2010 Shanghai World Expo is called "creative Pavilion", which looks like a colorful cube. First, we need to make a model of "British Pavilion" with the edge length of 6 × 10 & sup2; mm, and try to find out the volume of the model? 2. Given that x = - 4, y = 1 / 4, we can find the value of two times of X, x times of X and Y times of Y

1. 600 × 600 × 600 = 2.16 × 10 ^ 8 cubic millimeter = 2.16 × 10 ^ 5 cubic centimeter = 216 cubic decimeter
2、x^2*x^x*(y^(x+1))^2=-4^2*-4^-4*((4^-1)^-3)^2=4^(2-4)*4^6=4^4=256
