Does anyone know how to solve this equation to find M?

I know how to do it using a calculator but not quite understanding how to solve for the /powers when the results come up as 1^-11*10 (and the like).

F=GMm/d^2

Re-arrange --> M=Fd^2/Gm

Substitute --> M=12*(4*10^-6)^2/6.67*10^-11*1

F=12

G=6.67*10^-11

m=1

d=4*10^-6

--> d^2=(4*10^-6)^2

M=?

Thank you <3
