Answer 1

Answer:

Step-by-step explanation:

LET THE NUMBER OF TIMES LARGER = X

GIVEN:

8*10³= X 4*10²

X = 8*10³/4*10²

X = 2*10

THEREFORE:

20 TIMES LARGER.

For this case we can rewrite the expressions as:

3 * 10 ^ {- 3} = 0.0033∗10

−3

=0.003

That is, we run the decimal three times to the left.

4 * 10 ^ {- 6} = 0.0000044∗10

−6

=0.000004

That is, we run the decimal six times to the left.

So:

0.003-0.000004 = 0.0029960.003−0.000004=0.002996

So, we have that 3 * 10 ^ {- 3}3∗10

−3

is 0.002996 times bigger than 4 * 10 ^ {- 6}4∗10

−6

3 * 10 ^ {- 3}3∗10

−3

is 0.002996 times bigger than 4 * 10 ^ {- 6}4∗10

−6
