Answer 1

you need a caculater that is what you need tho

Answer 2

Answer:

70 × 6000 = 420000

Step-by-step explanation:

In this question, we need to write the product of two numbers 70 × 6000 using associative and commutative properties.

Two numbers are commutative if,

a × b = b × a

Two numbers are associative if,

(a × b) × c = a × (b × c)

Here, $70\times 6000=(7\times 10)\times (6\times 1000)$

$70\times 6000=7\times 10\times 6\times 1000$

Using commutative property as,

$70\times 6000=7\times 6\times 10\times 1000$

Now using associative property as,

$70\times 6000=42\times (10\times 1000)$

$70\times 6000=42\times (10000)$

$70\times 6000=420000$

So, 70 × 6000 = 420000. Hence, this is the required solution.
