Find the number from each of the following expanded forms:
`3xx10^(4)+7xx10^(2)+5xx10^0`

Answer

To solve the problem of finding the number from the expanded form \(3 \times 10^{4} + 7 \times 10^{2} + 5 \times 10^{0}\), we will follow these steps:

### Step 1: Calculate \(3 \times 10^{4}\)
First, we need to evaluate \(10^{4}\):
\[ 10^{4} = 10 \times 10 \times 10 \times 10 = 10000 \]
Now, multiply this by 3:
\[ 3 \times 10^{4} = 3 \times 10000 = 30000 \]

### Step 2: Calculate \(7 \times 10^{2}\)
Next, we evaluate \(10^{2}\):
\[ 10^{2} = 10 \times 10 = 100 \]
Now, multiply this by 7:
\[ 7 \times 10^{2} = 7 \times 100 = 700 \]

### Step 3: Calculate \(5 \times 10^{0}\)
Now, we evaluate \(10^{0}\):
\[ 10^{0} = 1 \quad \text{(Any non-zero number raised to the power of 0 is 1)} \]
Now, multiply this by 5:
\[ 5 \times 10^{0} = 5 \times 1 = 5 \]

### Step 4: Add all the results together
Now, we will add all the results from the previous steps:
\[ 30000 + 700 + 5 = 30705 \]

### Final Answer
Thus, the number from the expanded form \(3 \times 10^{4} + 7 \times 10^{2} + 5 \times 10^{0}\) is:
\[ \boxed{30705} \]
