3+x) 5<br> Solve it for me, and tell me how to do it EXPLANATION NEEDED
grigory [225]
I’m not too sure of what the equation is but I made a guess let me know if this was the right equation please I can redo it.

But, when solving this equation you are trying to find the value of x. To do that you have to get rid of the 3.

You would either add or subtract the 3 on both sides.

When the three is gone you should have somthing like

x = 5
- 3

Which you would move on to subtract the 5-3 and get 2.

x= 2

Here’s a picture of how I solved it

If x^y = z is there any way to find y if you know x and z?
Rzqust [24]

We make use of y = \log_x(z) to solve for y, when you know x and z

<h3>How to solve for y?</h3>

The expression is given as:

x^y = z

The above expression is an exponential expression.

Start by taking the logarithm of both sides

y log(x) = log(z)

Divide both sides by log(x)

y = \log_x(z)

Hence, we make use of y = \log_x(z) to solve for y, when you know x and z
