Use BODMAS or BIDMAS (Brackets, over Indices, Division, Multiplication, Addition, the Subtraction, this tells you which order to do things in)

As you cant do √10 in the brackets you do the indices, so (√10)³
Split this up to make it easier
(√10)³= √10 x √10 x √10 = 10√10

You the multiply this by 9

9 x 10√10 = 90√10

then multiply by 5

5 x 90√10 = 450√10 = 1423.024947 (using calculator)

The answers are 2. B, 3. D, 4. C, and 5. A.

Step-by-step explanation:

Step 1:

For question 2. $4+4n = -12.$

We subtract both sides by 4 to get

$4+4n-4 = -12-4, 4n = -16, n = -4$

For question 3. $4n=-12$ .

We divide the entire equation by 4 to get

$\frac{4n}{4} = \frac{-12}{4} , n = -3.$

Step 2:

For question 4. $\frac{n}{4} = -12.$

We multiply both sides by 4 to get

$\frac{n}{4} (4)= -12(4).$

$n = -48.$

For question 5. $\frac{n}{4} -4 = -12.$

We add 4 to both sides to get

$\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.$

$n = -32.$

So the answers are 2. B, 3. D, 4. C, and 5. A.
