1.а)
4^-2 • 16 = 4^-2 • 4^2 = 4^0 = 1
1.б)
2^8 : 2^-13 = 2^-5 = 1/32
1.в)
( 6^3 )^-3 : 6^-12 = 6^-9 : 6^-12 = 6^3 = 216
1.г)
24•2^-5 + 5^-2 • 125 = 24•2^-5 + 5 = (24/32) + 5 = 5,75
2)
1) y^9 • ( y^3 )^8 = y^9 • y^24 = y^33
2) ( y^5 )^6 = y^30
3) y^33 : y^30 = y^3
4) y = ( - 5 )
( - 5 )^3 = - 125
3)
52000000 = 5,2 • 10^7
0,00281 = 28,1 • 10^-4
