Question

I need help with my math

Answer 1

Consider the formula,

`x^m\cdot x^n=x^(m+n)`

The expression is given as,

`(2.3*10^4)(3*10^5)`

Solve the expression as,

`\begin{gathered} =(2.3*10^4)(3*10^5) \\ =2.3*10^4*3*10^5 \\ =2.3*3*10^4*10^5 \\ =6.9*10^(4+5) \\ =6.9*10^9 \end{gathered}`

Thus, the given expression is evaluated as,

`(2.3*10^4)(3*10^5)=6.9*10^9`
