Question

Please help me it is algebra and I need it evaluated

Answer 1

Explanation:

21)

Log 64 base 4

64=
`4^(X)`

`4^(3) =4^(X) \\\\The base cancels out\\3= X`

22)

`Log 16 base 4 = x\\\\16=4^(x) \\4^(2) =4^(x) \\`

The base will cancel out

2=x

30) Log 1/216 base 6

`(1)/(216) = 6^(x) \\\216^(-1) =6^(x) \\6^((3)(-1)) =6^(x) \\6^(-3) =6^(x)`

The base will cancel out

x=-3
