Solve1 over 25 = 5^x ^+ 4. <br> x = -7/2<br> x = −6 <br> x = 9/2 <br> x = 2
Basile [38]
The equation seems to be

   1
-------- = 5 ^ (x + 4)
  25

In that case, this is the solution, stept by step:

1) factor 25: 25 = 5^2

          1
=> ----------- = 5^(x + 4)
         5^2

2) invert 5^2

=> 5^(-2) = 5^(x+4)

3) Given that the bases are equal, the exponents also have to be equal:

=> - 2 = x + 4

3) transpose +4:

=> - 2 - 4 = x

=> x = - 6

Answer: - 6

PLEASE HELP QUICKLY IM VERY CONFUSED
Harman [31]

Answer:

42/90

Step-by-step explanation:

               <u>   </u>

Let x = .46

multiply both sides by 10

            <u>    </u>

10x = 4.66

multiply both sides by 10 again

                 <u>    </u>

100x = 46.66

                         <u>    </u>       <u>    </u>

100x - 10x = 46.66 - 4.66

90x = 42

x = 42 / 90

Can be reduced to x = 21/45
