Question

8^(2x) =11 help please

Answer 1

Use logarithms Logrithmic rules
1) log_b(mn) = log_b(m) + logb(n)

2) log_b(m/n) = log_b(m) – logb(n)

3) log_b(m^(n)) = n · log_b(m)

4) log_3(3) = 1

5) log_e(x) = ln(x)

6) log(x) = y is the same as x =10^(y)

7) log_10(x) = log(x)

8) log(x^(2)) = 2log(x)

Answer 2

take the log of both sides

log_8(8^(2x)) = log_8(11)

Now use rules I just gave you

Answer 3

hint* use rule 8

Answer 4

then rule 4
