ANSWER

Rewrite and make substitution.

EXPLANATION

Since Harriet calculated 27 divided 4 and had 6.75.

This means that:

\frac{27}{4}  = 6.75

Now we want to find

\frac{270}{4}

without divide.

Therefore we need to rewrite the expression so in terms of

\frac{27}{4}

so that we can substitute.

This will give us;

\frac{270}{4}  =  \frac{27}{4}  \times 10

This implies that,

\frac{270}{4}  =  6.75  \times 10

\frac{270}{4}  = 67.5

Which of the following numbers is both a perfect square and a perfect cube?
Marat540 [252]

Answer:

531441

Step-by-step explanation:

We can find by   factorization

531441 = 9 * 9 * 9 * 9 * 9 *9 = (9*9*9) * (9*9*9)

\sqrt[3]{531441}=\sqrt[3]{9*9*9*9*9*9}  =9*9 = 81\\\\\\\sqrt{531441}=\sqrt{(9*9)*(9*9)*(9*9)}=9*9*9=729
