Question 1030021
{{{ e^( 5x + 1 ) = e^16 }}}
The exponents must be equal
This is the same situation as if you had:
{{{ e^a = e^b }}}
{{{ a = b }}}
-----------------
So, I can say:
{{{ 5x + 1 = 16 }}}
{{{ 5x = 15 }}}
{{{ x = 3 }}}
-----------------
check answer:
{{{ e^( 5*3 + 1 ) = e^16 }}}
{{{ e^( 15 + 1 ) = e^16 }}}
{{{ e^16 = e^16 }}}
OK
