Petri did the following problem but got the wrong answer. she needs to correct her mistake and turn the problem back in.

(5 - 3) ^2 ÷ 3 • 7 + 1
25 - 9 ÷ 3 • 7 + 1
25 - 3 • 7 + 1
25 - 21 + 1
4 + 1
5

what correction does petri need to make?

she needs to subtract 5 - 3 first.
she needs to multiply 3 times 7 before she divides.
she needs to add before she multiplies.
she needs to change 25 to 10.

Petri needs to subtract 5 - 3 first.

Step-by-step explanation:

Given :

To Find : What correction does Petri need to make?

Solution:

Second step :

is the correct second step

While Petri's second step is 25 - 9 ÷ 3 • 7 + 1

Petri did mistake

She needs to subtract 5 - 3 first.
