What is the value of n in this equation: 2↑2 * 2↑n = (2↑4)↑3

Cloud [144]

Answer:

The value of n in the given equation is; n = 10

Step-by-step explanation:

Exponent for a natural power b is defined as iterated multiplication, which Knuth denoted by a single up-arrow:

a↑b = $a^b$ ......[1]

Given the expression: 2↑2 * 2↑n = (2↑4)↑3

Using [1] in the given expression is;

$(2^2) \cdot 2^n = (2^4)^3$

Using $a^n \cdot a^m = a^{n+m}$ and $(a^n)^m = a^{nm}$

we have;

$2^{2+n} = 2^{12}$

2 + n = 12 [ Using $a^m = a^n$ ⇒ m =n ]

Subtract 2 to both sides of an equation:

2 + n - 2 = 12 -2

Simplify:

n = 10

Therefore, the value of n is, 10

What is the midpoint of the segment shown below ?

umka21 [38]

Hey there! :)

Answer:

(5, 1/2)

Step-by-step explanation:

Recall that the midpoint formula is:

$(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Plug in the point values to solve for the midpoint:

$(\frac{5+5}{2}, \frac{-3+4}{2} )$

Simplify:

$(\frac{10}{2}, \frac{1}{2})$

(5, 1/2) is the midpoint.

what the total area of a rectangular prism with a hight of 17feet a width of 12 feet and a thickness of 10 feet ?

patriot [66]

Answer:

$A=988\ \text{feet}^2$

Step-by-step explanation:

Given that,

The height, width and the thickness of a rectangular prism are 17 feet, 12 feet and 10 feet.

We need to find the area of a rectangular prism. The formula for the ara of rectangular prism is given by :

$A=2(lb+bh+hl)$

Substitute all the values,

$A=2(17\times 12+12\times 10+10\times 17)\\\\A=2\times 494\\\\A=988\ \text{feet}^2$

So, the area of the rectangular prism is equal to $988\ \text{feet}^2$ .
