<u>Solution for question 1:</u>
Put it in this format:
Solving;
2(²-³) × 10^(15-9)
2^-1 × 10^6 = 1/2 × 10^6
That gives 5 × 10^5
<u>Solution to question 2:</u>
Solving;
2^(1 - 2) × 10^(-5 + 12)
= 1/2 × 10^7
That gives;
5 × 10^6
Answer:
12x + 18y + 6z + 4x - 4z
Step-by-step explanation:
Given the expression : 3(4x + 6y + 2z) + 4(x – z)
To eliminate the parenthesis ; we use the distributive property :
3(4x + 6y + 2z) + 4(x – z) becomes ;
3*4x + 3*6y + 3*2z + 4*x + 4*-z
12x + 18y + 6z + 4x - 4z
Hence,
12x + 4x + 18y + 6z - 4z
16x + 18y + 2z

Step 1 :
y
Simplify —
3
Equation at the end of step 1 :
y
((18 • (x2)) • —) • x
3
Step 2 :
Equation at the end of step 2 :
y
((2•32x2) • —) • x
3
Step 3 :
Dividing exponents :
3.1 32 divided by 31 = 3(2 - 1) = 31 = 3
Equation at the end of step 3 :
6x2y • x
Step 4 :
Multiplying exponential expressions :
4.1 x2 multiplied by x1 = x(2 + 1) = x3
Final result :
6x^3y
Using the arrangements formula, considering the given digits, it is found that Edward writes 6 numbers.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:
In this problem, the first digit has to be 5, while the other three are arranged, hence the total number of arrangements is given by:
