Medal and fan for help please help. Evaluate the expression: 5 + 3 × (5 - 2)2 16 32 36 72

OpenStudy (aripotta):

use PEMDAS

OpenStudy (aripotta):

do you know the order of operations?

OpenStudy (aripotta):

no :/

OpenStudy (aripotta):

5 + 3 × (5 - 2)2 Parentheses first: 5 + 3 x (3)^2 Exponents: 5 + 3 x 9 Multiplication: 5 + 27 Addition: 32

OpenStudy (justuu):

so the answer is 32?

OpenStudy (aripotta):

yes. do you understand how i got to it?

OpenStudy (justuu):

yeah

OpenStudy (aripotta):

PEMDAS is Parentheses Exponents Multiplication/Division Addition/Subtraction if you do it in any other order, you'll get a wrong answer

OpenStudy (justuu):

okay thank you
