A6. Let $m>1$. What do we get if we simplify the expression $m^{0.5}: \sqrt{m^{-\frac{3}{4}}} \cdot m^{\frac{1}{8}}$?
(A) 1
(B) $m^{2}$
(C) $m^{-1}$
(D) $m$
(E) -1
A6. We simplify the expression by writing the exponents as fractions $m^{\frac{1}{2}}: m^{-\frac{3}{8}} \cdot m^{\frac{1}{8}}$. We apply the rules for calculating with powers $m^{\frac{1}{2}+\frac{3}{8}+\frac{1}{8}}=m^{\frac{4+3+1}{8}}$ and obtain the solution $m$.
