Answer:

Solve for radius

radius = 10

Answer:

Step-by-step explanation:

$\huge {c}^{ \frac{1}{2} } + {c}^{ \frac{1}{3} } \\ \\ \huge = {64}^{ \frac{1}{2} } + {64}^{ \frac{1}{3} } \\(plug \: c = 64) \\ \\ \huge = { ({8}^{2}) }^{ \frac{1}{2} } + {( {4}^{3} )}^{ \frac{1}{3} } \\ \\ \huge = {8}^{2 \times \frac{1}{2} } + {4}^{3 \times \frac{1}{3} } \\ \\ \huge = 8 + 4 \\ \\ \huge = 12$

Find lcm of 14 and 28 in vertical method

guapka [62]

Answer:

Step-by-step explanation:

We will keep dividing by prime numbers until both are one (we will only consider whole divisions)

```

14 28 | 2

7 14 | 2

7 7 | 7

1 1

Now we multiply the left collumn, to get the LCM

2 * 2 * 7 = 28

And this was the vertical method, ok?
