Va rog ajutați-mă !

Answer 1

a)32^5:[-2^4x2^3]x8^2=(2^6)^5:(16x8)x64=2^30:(2^4x2^3)x2^7=2^30:2^14=2^16 b)16x-8=-128;-2^5=-32 c)81x3^7:-9^5=3^4x3^7:-9^5=3^11:-9^5=(3^2)^5,5:-9^5=9^5,5:-9^5=-9^0,5=-3 ;d)-125:-5^3x25=-125:-125x25=-125:-3125=0,04;e)15^75:-5^73:-3^73=15^75:-15^ 73=-5^2=25;f)-4^3:-4^2+-5^100:25^49-(-3^4)^5:(3^2)^10=4+25--3^20:3^20=29--1 =30
