Simplify -3√3(2+√6) please include steps

Mathematics
1 answer:
Nadusha1986 [10]3 years ago
8 0

Answer:

-6√3 - 9√2

Step-by-step explanation:

So you distribute like normal:

-3√3 times 2 is -6√3

-3√3 times √6 is -3√18

You can simplify -3√18 into -9√2

(because 9 can be squared into 3 and you can multiply the 3 with the current 3 into 9)

(Also you have to divide 9 out of 18 since you are simplifying)

So the answer will be -6√3-9√2

Hope this helps!

What is the answer to 1 2/3÷10+5​
ratelena [41]

Answer:

The answer is 5 1/6

Step-by-step explanation:

1 2/3 ÷ 10 + 5

5/3 ÷ 10/1 + 5/1

From the rule of BODMAS, we solve for division before subtraction

to change division to multiplication, 10/1 will become 1/10, then will we have

5/3 × 1/10 +  5/1

1/3 ×1/2 + 5/1

1/6 + 5/1

The common multiple of 6 and 1 is 6, so if we solve for the fraction, we will have

1/6 + 30/6 = 31/6

= 5 1/6
