Question

How do I solve 6^x-2=1/216 ?

Answer 1

x=-1

Explanation:

Write the number in exponential form with the base of 6

6^x-2 =6^-3

Since the bases are the same, set the exponents equal

x-2= -3

Move the constant to the right- hand side and change its sign

x= -3+2

Calculate the sum

x= -1
