Answer:
2/3a^5
Step-by-step explanation:
we know that 2/7x2/7x2/7 = 8/27
a^15 cube will be a^5
because we know (2^3)^2 = 2^6
so (a^5)^3 = a^15
2/3a^5

Answer:
2 1/2 cups
Step-by-step explanation:
5 × (1/2 cup) = 5/2 cup = 2 1/2 cup
__
Or, you can add them up. You know from your study of fractions that two half-cups make 1 cup.
(1/2 cup) + (1/2 cup) + (1/2 cup) + (1/2 cup) + (1/2 cup)
= ((1/2 cup) +(1/2 cup)) +((1/2 cup) +(1/2 cup)) +(1/2 cup)
= (1 cup) + (1 cup) + (1/2 cup)
= (2 cup) + (1/2 cup)
= 2 1/2 cup
