Answer 2

$\huge\textsf{Hey there!}$

$\text{Usually when you have a variable by itself it’s usually understood to be an INVISIBLE ONE}$

$\rm{d\timesd\times d \times d}$

$\rm{= 1d\times 1d \times1d\times1d}$

$\rm{= d^2 \times d^2}$

$\rm{= d^{2\times2}}$

$\rm{= d^4}$

$\huge\boxed{\mathsf{Therefore, \ your \ answer \ should \ be: d^4}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
