Объяснение:
a) 2^4*5^4 = (2*5)^4=10^4=10 000;
б) 4^3*25^3 = (4*25):3 = 100^3 = 1 000 000;
в) 0,25^15 * 4^15 = (0.25 * 4)^15 = 1^15=1;
г) (2/3)^7*1.5^7 = (2/3 * 1.5)^7 = 1^7=1;
д) (5/7)^10 * 1.4^9 = 5/7 * (5/7 * 1.4)^9 = 5/7*1^9 = 5/7;
е) 0.2^6 * 50^7 = (0.2*50)^6 * 50 = 10^6*50 = 1000000*50 = 50 000 000.
