Evaluate

$$64b^{2}a^{14}$$

Solution Steps

Expand \left(4a^{2}b\right)^{4}.

$$4^{4}\left(a^{2}\right)^{4}b^{4}\times \left(\frac{-a^{3}}{2b}\right)^{2}$$

To raise a power to another power, multiply the exponents. Multiply 2 and 4 to get 8.

$$4^{4}a^{8}b^{4}\times \left(\frac{-a^{3}}{2b}\right)^{2}$$

Calculate 4 to the power of 4 and get 256.

$$256a^{8}b^{4}\times \left(\frac{-a^{3}}{2b}\right)^{2}$$

To raise \frac{-a^{3}}{2b} to a power, raise both numerator and denominator to the power and then divide.

$$256a^{8}b^{4}\times \frac{\left(-a^{3}\right)^{2}}{\left(2b\right)^{2}}$$
