FMU Question 1 Use exponent rules to simplify the following, giving all answers with positive exponents. (a) \( 6^{3} \times 6^{-5} \times 6^{-2} \) \( 3+(5)+(-2)=3-5-2=3-7=\frac{1}{64}=6^{-4} \times 6^{-2}=\frac{1}{6} \) \( 6^{3} \times 6^{-5} \times 6^{-2}= \) (b) \( \quad-5\left(a^{3}\right)^{0}-3+4^{0} \)
