Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx

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
----> given problem
we have

substitute in the formula above

Remember that
![(64)^{\frac{2}{3}}=\sqrt[3]{(64)^2}=\sqrt[3]{(4^{3})^2}=\sqrt[3]{(4^{6})}=4^{2}=16](https://tex.z-dn.net/?f=%2864%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7B%2864%29%5E2%7D%3D%5Csqrt%5B3%5D%7B%284%5E%7B3%7D%29%5E2%7D%3D%5Csqrt%5B3%5D%7B%284%5E%7B6%7D%29%7D%3D4%5E%7B2%7D%3D16)
