Answer 1

$a).3^2^1*5^2^1-15^2^1=(3*5)^2^1-15^2^1=15^2^1-15^2^1=0 \\ \\ b).3^2^0*2^2^0-6^2^3:6^3=(3*2)^2^0-6^{23-3}=6^2^0-6^2^0=0 \\ \\ c).2^1^8*12^1^8:(6^1^6*4^1^6)=(2*12)^1^8:(6*4)^1^6=24^1^8:24^1^8=1 \\ \\ d).75^3^8:25^3^8-(3^1^9)^2=(75:25)^3^8-3^3^8=3^3^8-3^3^8=0 \\ \\ e).26^2^7:13^2^7: 2^{ 5^{2} } =(26:13)^2^7:2^2^5=2^2^7:2^2^5=2^{27-25}=2^2=4 \\ \\ f).10^6^4:2^6^4- 5^{ 4^{3} } =(10:2)^6^4-5^6^4=5^6^4-5^6^4=0$
