Answer:
-171
Step-by-step explanation:
Applying PEMDAS (order of operations),
We open the parenthesis first;
-9 - (
)³ × 6
-9 - 3³ × 6
We work on multiplication next;
-9 - 27 × 6 = -9 - 162
finally we do subtraction to get;
-9 - 162 = -171
Answer:
64
Step-by-step explanation:
16^1
---------------------- = 64
2 x 2 - ^3
Apply exponent rule
16^1 = 16
= 16
------------------
2x2 - ^3
16 = 2x 8
2 x 8
-----------
2 x 2 - ^3
Cancel the common factor <2>
8
---------
2-^3
Factor the number 8 = 2^3
2^3
----------
2-^3
Apply exponent rule.
= 2^3 - (-3) = 6
3- (-3) = 6
= 2^6
2^6 = 64
64 is the answer
9x -18 + 15 -6x = 2
3x -3= 2
3x= 5
X= 5/3
Hope this helps!
5x + 14 = 28
5x + 14 - 14 = 28 -14
5x = 14
5x/5 = 14/5
x = 2.8
