Dmitry [639]

For this case we must find the product of the following expression:

-3 \frac {1} {4} * - 1 \frac {1} {2} =

So, we have:

(\frac {4 * (3) +1} {4}) * (\frac {2 * (1) +1} {2}) =\\\frac {12 + 1} {4} * \frac {2 + 1} {2} =\\(- \frac {13} {4}) * (- \frac {3} {2}) =

By law of signs of multiplication is fulfilled:

- * - = +\\\frac {13 * 3} {4 * 2} =\\\frac {39} {8}

Write 56 as a product of primes.<br> Use index notation when giving your answer.
mixas84 [53]

Answer:

56 as a product of primes using index notation is: \mathbf{2^3 \times 7}

Step-by-step explanation:

We need to write 56 as a product of primes.

Prime Numbers:

<em>Numbers that are divisible by 1 or itself.</em>

Now, writing 56 as product of primes

56 = 2 x 2 x 2 x 7

Now, Use index notation when giving your answer.

Index Notation:

<em>Express elements in power form i.e. if we have 2 x 2 we can write it as 2^2</em>

So, answer will be:

56 = 2 \times 2 \times 2 \times 7

=2^3 \times 7

So, 56 as a product of primes using index notation is: \mathbf{2^3 \times 7}
