Odpowiedź:
1.a) 2^5-(-32)=
32-(-32)=
32+32=64
b)(3/2)^3 /(1/2)^4+1,5=
27/8 / 1/16 + 1,5=
27/8 * 16/1 + 1.5 =
27*2 + 1.5 = 54 + 1.5 = 55.5
c) 27 -4 -1 =22
d)9/25 - -9/5 + 3/25 - 1=
9/25 + 9/5 + 3/25 - 1 =
9/25 + 45/25 + 3/25 - 1=
57/25 - 1 =
2 7/25 - 1=
1 7/25 - 1 =
7/25
2. a) (3^2*3^9*3*3)/3^3=
3^14/3^3=
3^11
b) (7^11/7^2)/7^7=
7^9/7^7=
7^2
3. 1 - (2/3)^10
2 - (2/3)^5
3 - (3/2)^5
