Answer:
12
Step-by-step explanation:
[tex] \huge {c}^{ \frac{1}{2} } + {c}^{ \frac{1}{3} } \\ \\ \huge = {64}^{ \frac{1}{2} } + {64}^{ \frac{1}{3} } \\(plug \: c = 64) \\ \\ \huge = { ({8}^{2}) }^{ \frac{1}{2} } + {( {4}^{3} )}^{ \frac{1}{3} } \\ \\ \huge = {8}^{2 \times \frac{1}{2} } + {4}^{3 \times \frac{1}{3} } \\ \\ \huge = 8 + 4 \\ \\ \huge = 12[/tex]
