Integration

Integrate 4^x dx = 4^x /ln 4 + C where C is a constant

= 4^x /1.3863 + C (note: ln 4 = 1.3863)
= 0.7213 * (4^x ) + C

ln is the natural logarithm which is a logarithm with base e
/ denotes the division bar and * means multiply


Remember the formula:

Integrate a^x dx = a^x / ln a + C where a is numerical constant

Note: I don’t know how to enter integration sign on Yahoo editor.
I use the word integrate
