1) 3log25 + 10log16 - 11log3= 3log5^2 + 10log2^4 - 11log3= 6log5 + 40log2 - 11log3
2) loglog4(256) + log5(log6)= log4(log4(256)) + log5(log6)= log4(4) + log5(6)= 1 + log5(6)

1) 3log25 + 10log16 - 11log3
= 3log5^2 + 10log2^4 - 11log3
= 6log5 + 40log2 - 11log3
2) loglog4(256) + log5(log6)
= log4(log4(256)) + log5(log6)
= log4(4) + log5(6)
= 1 + log5(6)
3) log2(log5) + log(log3(27))
= log2(log5) + log(log3(3^3))
= log2(log5) + log(3)
= log2(log5) + 1
