指數記數法

1.(-10a<6> b<9>)<4>
=-10a<24> b<36>
_______________________________________________________________
2.(3a<2> b<9> ÷5c<6>)<4>
=3a<8> b<36> ÷ 5c<24>
=3a<8> b<36> / 5c<24>

<1> <2> <3> <4> <5> <6> <7> <8> <9> <10>= 指數

1. (-10a^6 b^9)^4
=10^4a^24 b^36
=10000a^24 b^36
2. (3a^2 b^9/5c^6)^4
=12a^8 b^36/625c^24

1.
(-1)④(10)④(a⑥)④(b⑨)④
=10000 a^24 b^36
2.
3④(a②)④(b⑨)④/[5④(c⑥)④]
=81/625 a^8 b^36 c^(-24)
