✔ 最佳答案
4(3+5)² = 4(8²) = 4*64 = 256order of operations: PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
3+5 is inside parentheses, so do that first
then sqare it due to the 2 being an exponent (i assume this is the case)
then multiply by 4
if the 2 is not an exponent, then its 4(8)(2) = 64

If just to simplify:
= 4([3 + 5]²)
= 4(8²)
= 4(64)
= 256
Answer: 256
= 4([3 + 5]²)
= 4(8²)
= 4(64)
= 256

You always start by completing what's in the parentheses, then work left to right. So:
4(3+5)2 = 4(8)2 = 4*8*2 = 32*2 = 64
4(3+5)2 = 4(8)2 = 4*8*2 = 32*2 = 64

Assuming question is :-
4(3 + 5)²
4 x 8²
4 x 64
256
4(3 + 5)²
4 x 8²
4 x 64
256

4(3+5)2
= 8(3 + 5)
= 8 x 8
= 64
or
4(3+5)2
= 8(3 + 5)
= 8 x 3 + 8 x5
= 24 + 40
= 64
or
4(3+5)2
= (4 x 3 + 4 x 5)2
= (12 + 20)2
= (32)2
= 64
whatever u like.
= 8(3 + 5)
= 8 x 8
= 64
or
4(3+5)2
= 8(3 + 5)
= 8 x 3 + 8 x5
= 24 + 40
= 64
or
4(3+5)2
= (4 x 3 + 4 x 5)2
= (12 + 20)2
= (32)2
= 64
whatever u like.

4(3+5)2
do you mean 4 times (3+5) squared?
4(3+5)^2
4(8)^2
4(64)
256

after seeing the first answer i got confused but i would have said add the brackets first so 4*8*2=64.
not sure now tho.
see what else you get
x

4(3 + 5)^2
= 4(8)(8)
= 4(64)
= 256
= 4(8)(8)
= 4(64)
= 256

hey mitch it is easy.4(3+5)2=4(8)2=4(64)=256
if 2 is not an exponent then the answer is 4(8)2=16*4=64
if 2 is not an exponent then the answer is 4(8)2=16*4=64
2008-03-19 4:36 pm
Assuming the 2 at the end means "squared"..........
3+5 = 8
8^2 = 64
4*64 = 256
3+5 = 8
8^2 = 64
4*64 = 256
