balu736 [363]

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
