Answer:

Option c

Step-by-step explanation:

Given is a number in base 8

The number is $1046$

We have to convert it into decimal number i.e. base 10

We know that any number has value as

$Unit digit (1) +tenth digit (a) + 100th digit (a^2) +1000th digit (a^3)$

where a may take values as 8 or 10 according to base

Hence the given number

$1046 = 1(8^3)+0(8^2)+4(8)+6\\= 512+32+6\\= 550$

Thus in decimal this equals 550

Option c is right

The probability of it being greater than 6 is 3/4.

I need to simplify this

Hi there!

$3 \sqrt{54} + 2 \sqrt{24} =$
First we split up the square root into two parts.

$3 \times \sqrt{9} \times \sqrt{6} + 2 \times \sqrt{4} \times \sqrt{6} =$
Now we calculate the value of the square roots which have an integer as a solution

$3 \times 3 \times \sqrt{6} + 2 \times 2 \times \sqrt{6} =$
Multiplying the integers gives us our next step.

$9 \sqrt{6} + 4 \sqrt{6} =$
And finally we add up the roots.

$13 \sqrt{6}$
