2. what is the smallest integer a such that a√115 will be greater than 115


Subject: Numbering

aV115 >= 115
a >= 115 / V115
a >= V115
The integer that greater than V115 is 11 (whose squared number is 121)

V = square root/akar kuadrat

3. Find the smallest integer a such that 945a is a perfect cube.


There is no smallest integer [tex]a[/tex] such that [tex]945a[/tex] is a perfect cube.
However, if [tex]a[/tex] or the perfect cube is a positive integer, the smallest integer a such that [tex]945a[/tex] is a perfect cube is 1225.

Explanation

Let [tex]b[/tex] be the root of the perfect cube which is the value of [tex]945a[/tex]. Thus,

[tex]\large\text{$\begin{aligned}b^3=945a\end{aligned}$}[/tex]

By prime factorization, we get:

[tex]\large\text{$\begin{aligned}b^3&=3\cdot315\cdot a\\&=3\cdot3\cdot105\cdot a\\&=3\cdot3\cdot3\cdot35\cdot a\\&=3^3\cdot5\cdot7\cdot a\\\end{aligned}$}[/tex]

The integer [tex]a[/tex] should be in the form of [tex]{}\pm 35^{(3k-1)}[/tex], [tex]k=1,2,3,{\dots}[/tex]. Unlike perfect squares, perfect cubes could be negative. Hence, temporary solution we can get is:

[tex]\large\text{$\begin{aligned}&a=-\left(35^{(3k-1)}\right )\\&\quad k=1,2,3,{\dots}\end{aligned}$}[/tex]

The larger the [tex]k[/tex] is, the smaller the [tex]a[/tex] will be.

THEREFORE, there is no smallest integer [tex]a[/tex] such that [tex]945a[/tex] is a perfect cube.

However, if [tex]a[/tex] or the perfect cube is a positive integer, the smallest integer [tex]a[/tex] such that [tex]945a[/tex] is a perfect cube is:

[tex]\large\text{$\begin{aligned}a&=35^{(3\cdot1\:-\:1)}\\&=35^2\\&=\bf1225\end{aligned}$}[/tex]

[tex]\blacksquare[/tex]

Jawaban:

9797

Penjelasan dengan langkah-langkah:

Solution :

Find smallest two prime number above 90 :

97 and 101

then

97 × 101 = 9797

So, the number is 9797


12. 4. Let P(n) be the statement that 13 +23 +···+n3 = (n(n+1)/2)2 for the positive integer n. a) What is the statement P(1)? b) Show that P(1) is true, completing the basis step of the proof. c) What is the inductive hypothesis? d) What do you need to prove in the inductive step? e) Complete the inductive step, identifying where you use the inductive hypothesis. f) Explain why these steps show that this formula is true whenever n is a positive integer. mohon bantuannya ya kaka , aku udah bingng banget dikumpul besok :(


a. P(1) is 1³ = (1(1+1)/2)²

b.1³ = 1
and (1(1+1)/2)² = (2/2)² = 1² = 1 thus P(1) is true

c. The inductive hypothesis is 1³ + ... + n³ = (n(n+1)/2)²

D. You need to prove P(n+1) so
1³ + ... + n³ + (n+1)³ = ((n+1)(n+1+1)/2)² = ((n+1)(n+2)/2)²

E. 1³ + ... + n³ + (n+1)³ = (n(n+1)/2)² + (n+1)³
= n²(n+1)²/4 + (n+1)³
= (n+1)² [n²/4 + (n+1)]
= (n+1)² [(n² + 4n + 4)/4]
= (n+1)² (n+2)² / 4 = ((n+1)(n+2)/2)²

F. So, if P(n) is true, then P(n+1) is true
Thus P(n) is true for all positive integer n.

14. If N be the positive integer such that the sum of its two smallest factors is 3 and the sum of its two largest factors is 294, then the value of N is?.


The value of N is 196. To solve this problem, we use the formula for the factors of the number N.

Penjelasan dengan langkah-langkah:

Is known:

If N be the positive integer such that the sum of its two smallest factors is 3 and the sum of its two largest factors is 294,

Asked

Then the value of N is?

Answer:

Suppose the factors are a, b, c and d.

a + b = 3

c + d = 294

a x d = b x c

We are looking for the sum of 2 integers whose result is 3.

1 + 2 = 3

so that a = 1 and b = 3

a x d = b x c

1 x d = 2 x c

d = 2c

c + d = 294

c + 2c = 294

3c = 294

c = 294 : 3

c = 98

c + d = 294

98 + d = 294

d = 294 - 98

d = 196.

N = a x d = 1 x 196 = 196.
