Struggling in these exponential functions
I have a problem with these problems can anyone help me and explain their answers? Thanks in advance.
1. 8^x = 16

2. 6^x 1/216

3. 8^2x-2=32^x-3

1. 8^x = 16

2. (6^x)(1/216)

3. 8^(2x-2)=32^(x-3)

1. $(2^3)^x = 2^4$

$x = ?$

2. $\frac{6^x}{6^3} = \, ?$

3. $(2^3)^{2x-2} = (2^5)^{x-3}$

$x = ?$

next time, use (grouping symbols) to make your syntax clear.
