Question

Solve for x
2^x= 0.0625(X is an integer)

Answer 1

Answer=x=-4

This question is to do with logs and indices

2^x =0.0625

we know that 2³=8
And log2(8) = 3

*using this form we can solve for x*

2³=8
2^x =0.0625

log?(?) = ?

Both indices have a base of 2 so the log2 stays the same

Instead of 8 we put the 0.0625 in the bracket

So we get
log2(0.0625) = ?
Put this in your calculator and you should get

log2(0.0625) = -4

Answer 2

there you go:)
