Use PEMDAS (parenthesis, exponents, multiply, divide, add, subtract)so first do 5 to the 2nd power. (5 x 5 = 25) so now you have:25-3*4Next do 3*4 =12Now you have 25-12 = 13Answer: 13

PEMDAS (Parentheses, Exponents, Multiplication, Division, Add, Subtract)So first you find out was 5^2 is. 5^2 = 5 times 5 = 25.so now you have 25 - 3*4so now you find 3*4 which equals 12.25-12= 17. theres your answer! hope this helped! :D

Sorry. that equals 13 not 17. lol. my bad. i was thinking of 17 - 12 which equals 5 and... ya. my brain works funny. lol

Always use the order of operations (PEMDAS).5^2 is 5*5, so it's 25.25 - (3*4) =25- 12 = 17.Just make sure to use the order of operations for any complicated equation you encounter.

first you would square five to get 25. Then multiply three by four to get twelve. finally subtract 12 from 25 to get 13
