Question 1) When multiplying powers with the same base, keep the base and _______________ the exponents.
nika2105 [10]

The rules are

x^a\cdot x^b = x^{a+b}

\dfrac{x^a}{x^b} = x^{a-b}

Let me show you why with a couple of examples: suppose we want to multiply

4^3\cdot 4^2

Since powers are just repeated multiplications, we have

4^3\cdot 4^2 = \underbrace{4\cdot 4\cdot 4}_{4^3}\cdot\underbrace{4\cdot 4}_{4^2}=4^5 = 4^{3+2}

Similarly, we have

\dfrac{4^3}{4^2} = \dfrac{4\cdot 4 \cdot 4}{4\cdot 4} = 4 = 4^1 = 4^{3-2}

Please Answer the 27the question I will mark you as the brainlest
kondor19780726 [428]

Answer:

Step-by-step explanation:

1) we have to find the area of the cut out portion

Since both circles in one side makes up the side 28cm

The diameter of each circle is 14cm

radius = diameter / 2

r = 7cm

Area of a circle = πr²

A = 22/7 × 7²

= 22/7 × 7 × 7

= 22 × 7 = 154cm²

So the four circles will make

= 154 + 154 + 154 + 154

= 616 cm²

The Area of the square will be

= L × L

= 28 × 28

= 784 cm²

Therefore the area of the remaining portion will be

Area of the square - total area of the circles

= 784 cm² - 616 cm²

= 168 cm²

The area of the remaining part is 168 cm²

snow_tiger [21]
40 cm = 400 mm, so 400 mm / 18 mm = 200:9, or 22.22:1.
