Fill in the blanks to obtain the sum expressed in scientific notation a. $$ 4.5 	imes 10^{1}+2.7 	imes 10^{1}=7.2 	imes 10^{1} $$

To fill in the blanks for the sum expressed in scientific notation, we can follow the steps of adding the two numbers in scientific notation.

Given:
- $$ 4.5 \times 10^{1} $$
- $$ 2.7 \times 10^{1} $$

Since both numbers have the same exponent (10^1), we can add the coefficients directly:

$$
4.5 + 2.7 = 7.2
$$

Now, we can express the sum in scientific notation:

$$
7.2 \times 10^{1}
$$

Thus, the completed statement is:

$$ 4.5 \times 10^{1} + 2.7 \times 10^{1} = 7.2 \times 10^{1} $$
$$ 4.5 \times 10^{1} + 2.7 \times 10^{1} = 7.2 \times 10^{1} $$
