1. (a^4 b^2)X(a^3 b^3)
=a^7 b^5
2. 16m^3 n^2 / 2m^2 n^2
=8m
3. 4p^4 q^2 X pq^3
=4p^5 q^5
4. 5X10四次+3X10二次+6
=5X10000+3X100+6
=50000+300+6
=50306
5. 1X2六次+1X2四次+1X2三次
=64+16+8
=88
=1011000(2)
6. 2601
=2x10^3+6x10^2+0x10+1x1
=a^7 b^5
2. 16m^3 n^2 / 2m^2 n^2
=8m
3. 4p^4 q^2 X pq^3
=4p^5 q^5
4. 5X10四次+3X10二次+6
=5X10000+3X100+6
=50000+300+6
=50306
5. 1X2六次+1X2四次+1X2三次
=64+16+8
=88
=1011000(2)
6. 2601
=2x10^3+6x10^2+0x10+1x1
