Question 895803: i just wan to make sure i am right
evaluate each expression according to the order of operations. show all work
1) 36/4*3
36/12
= 3
2)2*3^3-1
2*9-1
18-1
=1
3)2*(4+1)^2
2*5^2
2*25
=50
4)square root (4+12) * 3
squqare root 16*3

evaluate each expression according to the order of operations. show all work
1) 36/4*3
36/12
= 3
---
do the multiplication and division first.
multiplication and division are on the same level.
you do them left to right.
36/4*3 = (36/4) * 3 = 9*3 = 27
you got this one wrong.
2)2*3^3-1
2*9-1
18-1
=1
---
do the roots and exponents first.
then the multiplication and division.
then the addition and subtraction.
you got this one right.
3)2*(4+1)^2
2*5^2
2*25
=50
---
do what's in the parentheses first,
then the roots and exponents
then the multiplication and division
you got this one right.
4)square root (4+12) * 3
square root 16*3
256*3
= 768
---
do what's in the parentheses first.
then the roots and exponents.
roots and exponents are on the same level and are done left to right.
then the multiplication and division.
square root (4+12) * 3
= square root(16) * 3
= 4*3
= 12
you squared instead of getting the square root of.
you got this one wrong.
find the prime factorization of the following numbers. write the answers two ways with and without exponents
5)84
2^2 * 3 * 7
and
2*2*3*7
---
correct.
6)80
2*2*2*2*5
and 2^4*5
---
correct.
7) 540
2*2*3*3*3*5
and 2^2*3^3*5
---
correct
