Question

Match each expression on the left with equivalent value on the right.85(10)100(85)80 x 50800 x 508,50085040,0004,000

Answer 1

Answer::

`\begin{gathered} 85\mleft(10\mright)\to850 \\ 100\mleft(85\mright)\to8,500 \\ 80*50\to4,000 \\ 800*50\to40,000 \end{gathered}`

Step-by-step explanation:

We evaluate the given expressions:

`\begin{gathered} 85\mleft(10\mright)=85*10=850 \\ 100(85)=100*85=8,500 \end{gathered}`

Next:

`\begin{gathered} 80*50=8*10*5*10 \\ =8*5*10*10 \\ =40*100 \\ =4,000 \end{gathered}`

Finally:

`\begin{gathered} 800*50=8*100*5*10 \\ =8*5*100*10 \\ =40*1000 \\ =40,000 \end{gathered}`

So the matched expressions are:

`\begin{gathered} 85\mleft(10\mright)\to850 \\ 100\mleft(85\mright)\to8,500 \\ 80*50\to4,000 \\ 800*50\to40,000 \end{gathered}`
