Answer:
Step-by-step explanation:
-4 + (5+6/ -6 × 5) -2
Solve the brackets first!
-4 + (11/ -30) -2
Add the -4 and -2
-6 + (-11/30)
[If you meant -2 multiplied by (-11/30) then , something like this, If not then continue after the bracket!:
-4 + (11/15)
(-60+11)/15
-49/15 Answer ]
Now,
-6 -11/30
(-180-11)/30
-191/30
Hope this helps!

(2^6)^-5 is the expression that should be multiplied
Considering 1.824 (2 being hundredth) it would mean that this is 1.82 <span />
Answer: 2*√18 + 3*√2 + √162 = 18*√2
Step-by-step explanation:
I guess that the equation is:
2*√18 + 3*√2 + √162
And we want to simplify it.
first 18 = 9*2
then we can write:
2*√18 = 2*√(9*2) = 2*3*√2 = 6*√2
and 162/9 = 18
then we can write:
√162 = √(9*18) = √9*√18 = 3√18
now we can use the previous step: √18 = 3*√2
and:
√162 = 3*(3*√2) = 9*√2
now we can write our equation as:
6√2 + 3√2 + 9√2 = (6 + 3 + 9)√2 = 18*√2
And now we can not simplify it further more, so here we end.
