Question

Biologists use a formula to estimate the mass of a

Answer 1

Answer:

The approximate mass of the brain of a mouse is 2 grams

Step-by-step explanation:

The correct question in the attached figure

Let

B -----> the  approximate mass B of the brain in grams

m ----> the mass of a  mammal's brain in grams

we know that

$B=\frac{1}{8}m^{\frac{2}{3}}$ ----> given problem

we have

$m=64\ g$

substitute in the formula above

$B=\frac{1}{8}(64)^{\frac{2}{3}}$

Remember that

$(64)^{\frac{2}{3}}=\sqrt[3]{(64)^2}=\sqrt[3]{(4^{3})^2}=\sqrt[3]{(4^{6})}=4^{2}=16$

$B=\frac{1}{8}(16)\\\\B=2\ g$
