Answer:

I THINK its the last one (8 root 10 to the power of 3x)

Step-by-step explanation:

A square root is the same thing as raising something to the 1/2. So the expression we have is (10^1/2)^3/4x.

Due to exponent rules we can multiply to get

10^3/8x which is the same thing as 10^3x/8

The 8 goes to the root and the 3x becomes the exponent

Which expressions are equivalent to 4^{-2} \cdot 7^{-2}4 −2 ⋅7 −2 4, start superscript, minus, 2, end superscript, dot, 7, start

PolarNik [594]

Answer:

Step-by-step explanation:

Given the expression 4^{-2}•7^{-2}. The following expression are equivalent to given expression on simplification.

Generally from indices, a^-b = 1/a^b. Applying this to the given expression we have:

4^{-2}•7^{-2} = 1/4^2 • 1/7^2

= 1/(4×4) • 1/(7×7)

= 1/16 • 1/49

= 1/(16×49)

= 1/784

the diagram shows 3 identical circles inside a rectangle. each circle touches the other two circles and the sides of the rectang

Sergio [31]

Answer:

2640mm

Step-by-step explanation:

I'm assuming you need the area of the rectangle which the circles don't take up.

First, to find the area of the whole rectangle:

length x width

to find length:

the length is 1 circle, therefore it is the diameter of the circle, which is 32 x 2 = 64mm

to find width:

the width is 3 circles, which is the radius 6 times, so 32 x 6 = 192mm

So, area of rectangle = 64 x 192 = 12288mm

Now to find the area the circles take up:

area of 1 circle =

$\pi \times {r}^{2}$

$\pi \times {32}^{2}$

$1024\pi$

As we have 3 circles, we multiply this by 3:

$1024\pi \times 3 = 3072\pi$

Finally we subtract the area of the three circles from the area of the rectangle:

$12288mm - 3072\pi = 2637$

As we need to round it to 3 significant figures, the answer is 2640mm

7/10 divide by 1/5 - 4/3 x 10/11

Karolina [17]

Answer:

(-340)/231

Step-by-step explanation:

Simplify the following:

((-34)/33)/(7/10)

Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:

(-34×10)/(33×7)

33×7 = 231:

(-34×10)/231

-34×10 = -340:

Answer: (-340)/231
