When multiplying exponents with the same base, we add them together, so \$\displaystyle 2^4 * 2^2
\$ is the same as\$\displaystyle 2^6\$

a) \$\displaystyle f^3g^2h^4 * f^2gh^3\$
\$\displaystyle = f^5g^3h^7\$

When you have any power to the power of a power, like \$\displaystyle (2^6)^4\$ you multiply the exponents so you would get \$\displaystyle 2^24\$
b) \$\displaystyle (a^3b^2)^3\$
=\$\displaystyle a^9b^6\$

When you are dividing with the same base, we subtract exponents so \$\displaystyle 2^3/2^2\$ is equal to \$\displaystyle 2^1\$ or \$\displaystyle 2\$
c) \$\displaystyle a^4bc^-2/a^5b^2c^3\$
=\$\displaystyle a^-1b^-1c^-5\$ those are negative exponents btw.
or =\$\displaystyle 1/a^1b^1c^5\$

May I ask you why you expect someone else to do your work?
That is not our job. It is your job. They are for you to do.
