(3 x 10^6) x (3 x 10^ 5)

OleMash [197]

Answer:

$9*10^{11}$

Step-by-step explanation:

we have

$(3*10^{6})*(3*10^{5})$

we know that

$(a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)}$ -----> the bases are multiplied and the exponents are added up

in this problem

$(3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}$

$=9*10^{11}$

This item is $9000 dollar and it is 90% off how much is the item? Step by step?

Daniel [21]

Answer:

The item costs $900 after the 90% off.

Step-by-step explanation:

After the 90% off discount, the item costs (100% - 90%) the cost of the original price.

Hence, $\$9000 \cdot (100\% - 90\%)$

$= \$9000 \cdot 10\%$

$= \$900$

Hope this helped!
