Mark studies a group of 30 whales. If each whale weighed approximately 3.8 x 105 pounds, find the total weight of all 30 whales.

Yakvenalex [24]

Answer:

$= 1.14 \times 10^{7}pounds$

Step-by-step explanation:

If each whales weighed

$3.8 \times {10}^{5}$

Then 30 whales weighed

$30 \times 3.8 \times {10}^{5}$

$=114 \times {10}^{5}$

$= 1.14 \times 10^{2} \times {10}^{10}$

Applying the law of indices we obtain

$= 1.14 \times 10^{(2+ 5)}$

$=1.14 \times 10^{7}pounds$
