never [62]

Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.

Step-by-step explanation:

Given: Weight of Blue whale = $3\times10^5\text{ pounds}$

Weight of Narwhal = $2\times10^3\text{ pounds}$

Number of times blue whale's weight is heavier than the narwhal's weight = $=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}$

$=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150$

Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

Kryger [21]

Answer:

$x^3-8$

Step-by-step explanation:

apply the inverse properties of logarithmic and exponential functions to simplify

$- 8 + e^{lnx^3}$

Inverse property of log says that

$e^{ln(x)=x$

we apply this property in our problem. ln has same base 'e' . so ln and e gets cancelled

$e^{ln(x^3)=x^3$

$- 8 + e^{lnx^3}$

$- 8 +x^3$

$x^3-8$
