Question

( 5^3.(3x+2) :13= 5^5:(13^5 :13^4)

Answer 1

\(\left[5^3.\left(3x+2\right)\right]:13=5^5:\left(13^5:13^4\right)\)

\(\left[5^3\left(3x+2\right)\right]:13=5^5:13\)

\(\left[5^3\left(3x+2\right)\right]:13=\frac{3125}{13}\)

\(\left[5^3\left(3x+2\right)\right]=3125\)

\(3x+2=3125:5^3\)

\(3x+2=25\)

\(3x=25-2\)

\(3x=23\)

\(x=\frac{23}{3}\)

Answer 2

 

\(5^3.\left(3x+2\right):13=5^5:\left(13^5:13^4\right)\)

\(5^3.\left(3x+2\right):13=3125:13\)

\(5^3.\left(3x+2\right):13=\frac{3125}{13}\)

125 . ( 3x + 2 ) : 13 =\(\frac{3125}{13}\)

125 . ( 3x + 2 ) =\(\frac{3125}{13}.\frac{13}{1}=3125\)

3x + 2              = 3125 : 125

3x + 2              = 25

3x                    = 25 -2

3x                    = 23

x                    =  23 : 3 

x                    = \(\frac{23}{3}\)
