Answer 1

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

Answer 2

Answer:

$u^{7}$

Step-by-step explanation:

In exponent multiplication, if  bases are same just add the exponents.

$a^{m}*a^{n}=a^{m+n}\\\\\\u^{3}*u^{3}*u = u^{3+3+1}=u^{7}$
