Answer:
[tex] = 1.14 \times 10^{7}pounds[/tex]
Step-by-step explanation:
If each whales weighed
[tex]3.8 \times {10}^{5} [/tex]
Then 30 whales weighed
[tex]30 \times 3.8 \times {10}^{5} [/tex]
[tex] =114 \times {10}^{5} [/tex]
[tex] = 1.14 \times 10^{2} \times {10}^{10} [/tex]
Applying the law of indices we obtain
[tex] = 1.14 \times 10^{(2+ 5)}[/tex]
[tex] =1.14 \times 10^{7}pounds[/tex]
