Answer:
1. 1
2. -12497.9953704
3. 728973030.3
Step-by-step explanation:
1. 8(xy) + 6^0x^0 - 10y^0 - xºyº + 5^3x^0 = 1/1 = 1
2. 6^2 + 6^-3 - 6° + 6^4 - 6^3(6 - 2) 3 = -2699567/
6^2 + 6^-3 - 6° + 6^4 - 6^3(6 - 2) 3 = -2699567/216
6^2 + 6^-3 - 6° + 6^4 - 6^3(6 - 2) 3 = -2699567/216 = -12497 215/
6^2 + 6^-3 - 6° + 6^4 - 6^3(6 - 2) 3 = -2699567/216 = -12497 215/216
6^2 + 6^-3 - 6° + 6^4 - 6^3(6 - 2) 3 = -2699567/216 = -12497 215/216 = -12497.9953704
3. 30° + 30 - 2(30^3) - 30^2 + 30^4(30^2) + 30^3 + 30^2 = 7289730303/
30° + 30 - 2(30^3) - 30^2 + 30^4(30^2) + 30^3 + 30^2 = 7289730303/10
30° + 30 - 2(30^3) - 30^2 + 30^4(30^2) + 30^3 + 30^2 = 7289730303/10 = 728973030 3/
30° + 30 - 2(30^3) - 30^2 + 30^4(30^2) + 30^3 + 30^2 = 7289730303/10 = 728973030 3/10
30° + 30 - 2(30^3) - 30^2 + 30^4(30^2) + 30^3 + 30^2 = 7289730303/10 = 728973030 3/10 = 728973030.3
