Require Guidance on Formula

[AzulRios]

I have a formula from ASCE 7 [ Ta = Ct * HnX ]

The X is superscript equals 0.75

Ct = 0.020

Hn = 20

I just cannot get the correct answer, of which, is 0.189

Please provide how to incorporate the "x" into the formula

Regards,

=0.02*(20^0.75)

Thanks for the quick response!!

Now, I need to get the symbol insert but struggling on the Mac

Detlef,

Finally got the symbol to work. Had to add some parentheses to sort it out.

Thanks
