/** * Seek the powers of a number * x^y,y is a positive integer.The calculator can only calculate two number multiplication, cannot calculate n number multiplication at one time.* Know: 2^5= (2^2) ^2*2; 2^6= (2^2) ^3= ((4) ^2); 2^8= (2^2) ^4= (4^2) ^2= 16^2 * Get the rule: x^y= (x^2) ^ (Y/2), define A=X^2,B=Y/2, then get shape such as: x^y= a^b; * y assumes an odd number, then the decomposition of the last multiplied by a (as above 2^6 decompos
