Answer: Rational "yes"

Step-by-step explanation: The square root of 25 is indeed a rational number. Rational numbers are numbers. The square root of 25 is a perfect square which means that it has a number that can be multiplied by itself which gives us 25.

In this case, the number is 5 so yes, it's rational.

Please help me with questions a, b, and c. Thank you

Answer:

A: Not rational, because a rational number is any integer, fraction, terminating decimal, or repeating decimal. This does not show that.

B: In between 13 and 15, (200 rooted is 14.1) I know this because if you simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

C: He should make each side about 3.76 feet long. Because, 3.76^4 is 200, therefore it would become 200 square feet if each side is 3.76 feet long.

Simplify. Write the expression using only positive exponents. 3d^−4⋅4d^4 PPPLLLLEEEASSSEEEEE
bixtya [17]

Answer:

d=0

Step-by-step explanation:

Because multiplication is commutative, we can rearrange the expression however we want. So, let's put the constant expressions together, and the variable expressions together:

(3 x 4) x (d^-4 x d^4)

The first term is easy enough: (3 x 4) = 12

For the second term, when exponent terms have the same "base" (in this case, d), the exponents can be added together. So, the second term yields d^(-4 + 4) = d^0. Any number raised to the zero power equals 1, EXCEPT for the sole number of zero. 0^0 is undefined, but any other number raised to the zero power equals 1.

So, if d equals any number other than zero, the expression becomes

(12) x (1) = 12

The best way to express the answer would be that the expression equals 12 except that it is undefined if d=0

Daniel [21]

Answer:

54

Step-by-step explanation:

I'm assuming the equation looks like this: 15x - 6

15*4 - 6

60 - 6

54

OR if it's just x-6 then the answer is -2

Hope this is what you were asking, have a nice day! :)
