Mathematics ability of the first grade in junior high school
From the a power of 10 = the b power of 20, the a power of 10 = 15, and the b power of 10 = 10 * 10 squared. The power of a=b+2 .3 = the power of 3 * the square of 3. So the a power of 3/the b power of 3 = the b power of 3 * the square of 3/the b power of 3 = the square of 3 =9.
