Question

Evaluate.7^2−3+9×8÷2=

Answer 1

82

Step-by-step explanation

To evaluate this expression, we have to follow the order of operations:

• Parentheses,: solve the expressions inside the parentheses first

,

• Exponents,: solve the exponents and roots second

,

• Multiplication, and ,Division,: solve multiplications and divisions next, from left to right

,

• Subtraction, and ,Addition,: solve subtractions and additions last

In this expression, there are no parentheses, but there is one exponent. Solve that one first,

`7^2-3+9*8/2=49-3+9*8/2`

Now, we have to solve the multiplication and then the division in the last term of the expression, in that order,

`49-3+(9*8)/2=49-3+72/2=49-3+36`

Now, solve the subtraction and then the addition,

`49-3+36=46+36=82`

Hence, the result is 82.
