a 6^3x6^2x6^4
=6^3+2+4
=6^9
b a^3xa^2:a^4
= a^3xa^2xa^-4
= a^3+2-4
=a^1
c b^9:b^4xb^3
= b^9xb^-4xb^3
= b^9-4+3
= b^8
d 3^7:(3^4x3^2)
= 3^7:3^6
= 3^7-6
= 3
e X^4x(X^6:X^3)
= X^4xX^6-3
= X^4xX^3
= X^4+3
= X^7
f b^8:(b^4xb^4)
= b^8:(b^4+4)
= b^8:b^8
=1

a (2^4)^3
= 2^4x3
= 2^12
b (3^2x3^4)^3
= (3^2+4)^3
= (3^6)^3
= 3^18
c (6^3x6^5)^2
= (6^3+5)^2
= (6^8)^2
= 6^16
d (7^9:7^4)^3
= (7^9-4)^3
= (7^5)^3
=7^15
e (2^3)^2x(2^4)^3
= 2^6x2^12
= 2^6+12
=2^18
