just need to know what the u term is. i know how to evaluate after that. int((7^sqrt(x))*ln(7))/2*sqrt(x)) x: 4,2

Answer 1

lana, can you use equation to write your question?

Answer 2

\[\int\limits_{2}^{4}7\sqrt{x}(\frac{\ln 7}{2\sqrt{x}})\]

Answer 3

Is that the question?

Answer 4

Yeah, that's the question

Answer 5

\[\int\limits_{2}^{4}7^{\sqrt{x}}(\frac{\ln 7}{2\sqrt{2})}\]

Answer 6

Or is it that?

Answer 7

Whoops. Make that an x in the denominator

Answer 8

I don't think the asker know which one is correct!

Answer 9

the 1st one is correct

Answer 10

If the first one is correct, cancel out the sqrtx and you are left with only constants.

Answer 11

ok, thanks

Answer 12

= (14 ln7/9) [ 4^(9/14 - 2 ^(9/14) ] + C

Answer 13

I thought it is x^(1/7) and x^(1/2) ?

Answer 14

So confused!
