We have shown that 268 can be written as the sum of a power of 3 and a squared number.

We are given a number:

268

We need to show that it can be written as the sum of a power of 3 and a squared number.

We can write 268 as:

268 = 243 + 25
Now, factors of:

243 = 3 × 3 × 3 × 3 × 3

25 = 5 × 5

So, this can be rewritten as:

268 = 3 ⁵ + 5²

which is he sum of a power of 3 and a squared number

Therefore, we have shown that 268 can be written as the sum of a power of 3 and a squared number.

The square root of 11 and 62 to the nearest tenth is 7.9 and 3.3 .

Given, the numbers are 11 and 62.

we are asked to determine the square root of the given numbers to the nearest tenth.

a. 11

Since the given number is not an even number, hence we can't get a whole number as the square root of 11.

we need to find the number whose square root is nearest to the number 11.

3 × 3= 9

9 is nearer to 11 whereas 4 × 4 = 16 gets greater than 11.

then dividing the number 11 by 3.we get:

√11 = 3.31662479  × 3.316622479

√11 = 3.31662479

√11 = 3.4 (rounding off to the nearest tenth)

b.  62

since we can't get the square root as a whole number so ,

we need to find the number whose square root is nearest to the number 62.

8 × 8 = 64

which gets greater than 62, hence we take 7 × 7 = 49

therefore, √62 = 7.874007874 × 7.874007874

√62 = 7.874007874

√62 = 7.9 (rounding off to the nearest tenth)

hence we get the square root of 11 and 62 as 3.3 and 7.9 respectively.

Answer:

9 , 16x^2 , 4z and 100y^2 are perfect Squares!

_____________________________________
What are Perfect Squares?

A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer.

3 * 3 = 9
4 * 4 = 16
2 * 2 = 4
50 * 50 = 100

Therefore making those numbers perfect squares.

AB = 39

AC = 24

Step-by-step explanation:

The sum of AB and BC is equal to the length of AC.

We can write the following equation based on this information :

AB + BC = AB rewrite the equation using given values

4x - 9 + 3x - 12 = 63 add like terms

7x - 21 = 63 add 21 to both sides

7x = 84 divide both sides by 7

x = 12 replace x with 12 in each expression to find the lengths

AB = 4x-9

AB = 4•12 - 9 and

AB = 39

BC = 3x -12

BC = 3•12-12 and

Cavitation reduces a tree's ability to conduct water due to the formation of air bubbles in water, thereby reducing the hydraulic conductance of the tree.

Cavitation, also known as embolism, is said to occur when the tracheid or vessels of the xylem is being filled with bubbles of air. Cavitation is what is said to occur when air bubbles form in water during transpiration.

The effect of cavitation is the prevention of the upward pull of water, leading to a degradation of hydraulic conductance, such that the xylem water potential is reduced.

Now,

=> Sum of all the values = 590.1+590.2+590.3+590.4+590.5+590.6+590.7+590.8 = 4723.6

=> Since 8 data values are present,

=> Mean = 4723.6/8 = 590.45

=> 590.1 - 590.45 = -0.35;

=> (-0.35)² = 0.1225

=> 590.2 - 590.45 = -0.25;

=> (-0.25)² = 0.0625

=> 590.3-590.45 = -0.15;

=> (-0.15)² = 0.0225

=> 590.4-590.45 = -0.05;

=> (-0.05)² = 0.0025

=> 590.5-590.45 = 0.05;

=> (0.05)² = 0.0025

=> 590.6-590.45 = 0.15;
