Answer:

7*10*10*10 = 7000

7*10 = 70

70*10 = 700

700*10 = 7000

Step-by-step explanation:

The given expression is:

7*10^3

Here 10^3 means that 10 will be multiplied 3 times:

7*10*10*10 = 7000

How did we get 7000?

7*10*10*10 = 7000

7*10 = 70

70*10 = 700

700*10 = 7000

We can also say that there are 7  1000s in 7000....

Answer: Hi! the notation 7×10^3 means 7*10*10*10, where 3 is the exponent.

You can think this notation as how many zeros you can add to the left (or right if the exponent is negative) of a number.

so 7×10^3 has an exponent equal to 3, so you add 3 zeros and get : 7000.

if we do the multiplication, 7*10*10*10 = (7*10)*10*10 = 70*10*10 = (70*10)*10 = 700*10 = 7000.
