I have created two macro variable (B0 and B3)this way...
............
data _null_;
set abc;
if variable="Intercept" then
call SYMPUTX("B0", estimate);
if variable="logX3" then
call SYMPUTX("B3", estimate);
run;
/* After this I have created a data set aa
as
data aa; m=&B0;n=&B1;run;
Found that both m and n are numeric-I have done this to check the variable types*/
Finally, I am interested to use these variables as
PROC NLIN Data=Prob20;
Parms gamma0 = 10**&B0 gamma3=&B3;
MODEL Y=gamma0*X3**(gamma3);
RUN;
But this what it returned
Here is the error message
Thanks in advance for any help.

Yes it can, wrap it in the %sysevalf function to resolve it.
parms gamm0=%sysevalf(10**&B0) gamm3=&b3;
ALL macro variables are character, so testing to see if they're numeric is pointless.

Thanks Reeza.
Appreciate your skills.

%let calc=%sysevalf(10**&b0.);
PROC NLIN Data=Prob20;
Parms gamma0 = &calc. gamma3=&B3;
MODEL Y=gamma0*X3**(gamma3);
RUN;
Try this the return is without error for me except the table which is not existing.
the macro variable calc contain the exact TEXT that will be substituted in your parms instruction
AS Macro variable contains always text
and as it seems that exponient is not allowed
74 | Parms gamma0 =11**1 | gamma3=&B3; |
ERROR 200-322: The symbol is not recognized and will be ignored
