How do you use the order of operations to simplify expression with exponent

So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.

The order of operations is to solve what ever is in brackets (or Parentheses) and then exponents then division or multiplication from left to right then addition and subtraction from left to right an, easy way to remember all that is to remember the word BEDMAS

Jocelyn invested $390 in an account paying an interest rate of 2.7%

Katarina [22]

Answer:

There will be $634.05 in the account.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$390 in an account paying an interest rate of 2.7% compounded daily.

This means that $P = 390, r = 0.027, n = 365$
