Question

calculati utilizand regula a la puterea m : a la puterea n = a la puterea m- n : a)23 la puterea 7 : 23 la puterea2 : la 23 b) (2 la puterea 3) la puterea 5:2 la puterea 10 c) 11 la puterea 50: 11 la puterea 45- 11 la puterea 5. d) (3 la puterea 2* 3 la puterea 3*3 la puterea200): 9 la puterea103

Answer 1

a) 23^7:23^2:23=23^7-2-1 = 23^5-1=23^4

b) (2^3)^5:2^10 = 2^15:2^10=2^15-10=2^5

c) 11^50:11^45-11^5=11^50-45-11^5=11^5-11^5= 0

d)(3^2×3^3×3^200):9^103=3^2+3+200:9^103=3^205:9^10=3^205:(3^2)^10=3^205:3^20=3^205-20=2^185
