I DO NOT UNDERSTAND HOW TO MULTIPLIN WHAT IS IN MY PERENTHESSE BY THE POWERS MY PROBLEM IS A= 8350(1+0.052/12)^10*12
A= 8350(1+0.052/12)^10*12
A=8350(1 + 0.0043333)^120
A=8350(1.0043333)^120
A=8350(1.6801391)
A=$14,029.16
8350(1+0.052/12)^10*12
Should be written as 8350(1+0.052/12)^(10*12)
The brackets around the 10*12 are important.
Otherwise you would just take the power of 10 AND THEN multiply by 12 afterwards
So what guest has done is most likely what you wanted BUT it is not what you wrote.
