Answer:
x = 6
Explanation: 22 = 64
Just in case your teacher wants you to solve this the
fancy way... log 2 log 64
=
x log 2* log 64
x log 2 log 64
log 2
x = 6
log 2
Take the log of both sides Use the log rule log x = alog x
Divide both sides by log2
Or, if you're not allowed to use a calculator...
log₂ 2 = log₂ 64
x log₂ 2 x log₂ 2 log₂ 2 = log2 64 log₂ 64 log₂ 2
log₂ 64 = 6 because the answer to a log problem is the exponent 6 that will make the base 2 equal the
argument 64. In other words, 26 = 64. Similarly,
log₂ 2 = 1 because 2¹ = 2. But if you knew that, you could solve this problem without all the fancy math!
6 X =1
x = 6
