Final answer:
To solve the expression (2.4 x 10^3)+(5.7×10^2), we convert both terms to the same exponent for the power of ten, resulting in a final value of 2.97 x 10^3.
Step-by-step explanation:
The student asks for the value of the expression (2.4 x 10^3)+(5.7×10^2). To find this, we need to make sure both terms have the same exponent for the power of ten. We could convert 5.7×10^2 to the same exponent as the first term by expressing it as 0.57 x 10^3. Then, we can directly add the values:
(2.4 x 10^3) + (0.57 x 10^3) = (2.4 + 0.57) x 10^3 = 2.97 x 10^3
Thus, the value of the given expression is 2.97 x 10^3.
