simple year 8 maths question 10 POINTS!!!?

What is ever in the brackets always goes first.

5^2 = 25.

diff calcs diff results: Due to: Calc has no brackets.

How to resolve: First do -6 + 11, then square it.

(-6+11)^(2)

Add 11 to -6 to get 5.
(5)^(2)

Expand the exponent (2) to the expression.
(5^(2))

Squaring a number is the same as multiplying the number by itself (5*5).
(5*5)

Multiply 5 by 5 to get 25.
(25)

Remove the parentheses around the expression 25.
25

(-6 + 11)^2
= (11 - 6)^2
= 5^2
= 5 x 5
= 25

(+5)^2=25

yeah you do the parenthesis first, which is five, then you do the power so


(-6+11)^2
5^2=25

hope this helped :P

Yes, everyone else told you right. But in the UK (where I think you are), we are taught BODMAS, not PEMDAS
B=Brackets
O=Other (like squares etc.)
D=Divide
M=Multiply
A=Add
S=Subtraction

your answer should be 25
because with the "oder of operation" concept, you should do the math in parenthesis fist:
-6 + 11 = 5
5 is positive because when you add a positive number wit a negative number, the answer takes the sign of the highest number, in this case it's 11
then you are left with (5)^2 and you simply square the % by multiplying it by itself" 5X5= 25
answer should be 25

Okay, well you need to add what is in parenthesis first. Remember PEMDAS: parenthesis, exponents, multiplication, division, addition, subtraction.

(-6 + 11)^2 = (5)^2

5^2 can also be written as 5 * 5, which is 25.

(-6 + 11)^2 = 25

Yes, parenthesis go first.

(-6+11)^2

means

(5)^2

25

Yes you do inside the brackets first

-6+11 = 5

5^2 = 25

You always do Inside the parentheses first... thats why they are there
