Answer:
u⁷
Step-by-step explanation:
When multiply variables with exponents , all you do is add the exponents
so,
our powers are 3,3,1 (because no exponent means to the power of 1)
Adding the powers is 7
so u⁷
[tex]u^{7}[/tex]
In exponent multiplication, if bases are same just add the exponents.
[tex]a^{m}*a^{n}=a^{m+n}\\\\\\u^{3}*u^{3}*u = u^{3+3+1}=u^{7}[/tex]
