For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1

Complete the equation.<br> (4x)−2(4x)3(4x)9=(4x)
AVprozaik [17]

Given:

Consider the given equation is

(4x)^{-2}(4x)^3(4x)^9=(4x)^?

To find:

The missing value in the given equation and complete the equation.

Solution:

We have,

(4x)^{-2}(4x)^3(4x)^9=(4x)^?

Taking LHS, we get

LHS=(4x)^{-2}(4x)^3(4x)^9

LHS=(4x)^{-2+3+9}          [\because a^ma^n=a^{m+n}]

LHS=(4x)^{10}

and,

RHS=(4x)^?

Let the missing value be k.

For each equation LHS=RHS.

(4x)^{10}=(4x)^{k}

10=k

Therefore, the missing value is 10 and the complete equation is (4x)^{-2}(4x)^3(4x)^9=(4x)^{10}.

Serial numbers for a product are to be made using 3 letters followed by 3 digits. The letters are to be taken from the first 5 l
Bezzdna [24]

Answer:

43,200 serial numbers can be generated

Step-by-step explanation:

The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

How many serial numbers can be generated

3 letters, from the first five of the alphabet

3 digits, from a set of 10

So

T = P_{5,3}*P_{10,3} = \frac{5!}{(5-3)!}*\frac{10!}{(10-3)!} = 43200

43,200 serial numbers can be generated
