Which expression is equivalent to (4.5x10^2) + (6.0x10^3) and written in scientific notation?

A. 1.05 x 10^6
B 2.7 x 10^6
C. 6.45 x 10^3
D. 10.5 x 10^5

Answers

Your answer for this problem is c

The value of the expression (4.5 x 10²) + (6.0x10³) is 6.45 x 10³. Therefore, the correct option is C.

Scientific notation:

The given expression is the sum of two numbers written in scientific notation.

[tex](4.5\times 10^2)+(6.0\times 10^3)[/tex]

It can be written as:

[tex](0.45\times 10\times 10^2)+(6.0\times 10^3)[/tex]

[tex]=(0.45\times 10^3)+(6.0\times 10^3)[/tex]

[tex]=(0.45+6.0)\times 10^3[/tex]

[tex]=6.45\times 10^3[/tex]

The required expression in scientific notation is [tex]6.45\times 10^3[/tex].

Therefore, the correct option is C.
