Those who know C++, I require assistance!

Okay you C++ users! This requires some basic C++ knowledge.

Now, I'm making a problem for my Computer Programming class that, in a part, I need to write a function.

The function should be, in c++:

basal_metabolic_rate<double> = 70 * (weight/2.2)...

This is the part I'm making a mistake, and it's the power function. I know the power function is, for example, pow(x,y) for x to the power of y. But I'm having problems on raising that small part of "(weight/2.2)".. I should raise that to the power of 0.756

So if anyone knows how to write that small part of the function in C++, please tell me. This stupid lab is due tonight and I keep doing this small mistake.

basal_metabolic_rate<double> = 70 * (pow((weight/2.2),0.756))

would that work?

dont forget to #define <math.h> if your doing this.

you could also define a second variable to store (weight/2.2)

temp_var = (weight/2.2)

power = pow(temp_var,0.756)

basal_metabolic_rate<double> = 70 * power

messy, but might work

Thanks, but the problems were already submitted. But, I'll test it.
