Question

Evaluate using order of operation and please show work​

Answer 1

10

Explanation:

Given expression:

20 -
`(15 + 3(5)^(2) )/(5^(2) - 4^(2) )`

To solve this problem, we use the order of operation:

P - Parentheses

E - exponents

M - multiplication

D - division

A - Addition

S - Subtraction

Now solve the parentheses first;

= 20 -
`(15 + 3x 25)/(5^(2) - 4^(2) )`

= 20 -
`(15 + 75)/(5^(2) - 4^(2) )`

Now solve the exponents:

= 20 -
`(15 + 75)/(25 - 16)`

Now solve the division:

= 20 -
`(90)/(9)`

= 20 - 10

= 10
