Explain how finding 4 times 384 can help you find 4 times 5384.then find both products
forsale [732]

Answer:

Given the following: 4 times 384 can help you find 4 times 5384.

4 \times 384 = 1536                

Now, find 4 \times 5384

Using Distributive property: a\cdot (b+c) = a\cdot b + a\cdot c

We can write 4 \times 5384 as

4 \times (5000+384)

Apply distributive property we have;

4 \times 5000 + 4\times 384

Now, find both products;

we know:  4 \times 384 = 1536            

20000 + 1536 = 21,536
