Question

5^(y+2)=1

Answer 1

Why guess?
IS this \[5^{y+2}=1\]

or \[5^{y}+2=1\]

In the first case - take logs of both sides.

In the second case move the 'constant' terms to one side of the equation (careful with the signs) and THEN take logs (however - this will cause you a problem - so I guess the equation MUST be the first case)

Answer 2

the first one

Answer 3

take logs of both sides

then use the following identitiy:
\[\log(a)^{n}= nlog(a)\]

Answer 4

What's the question?

Answer 5

You just gave us an expression and not the question..

Answer 6

it says solve and check

Answer 7

solving exponential equations

Answer 8

There is however a more direct solution
\[n ^{x}=1\]
implies x=0
