Example Question #971 : Hspt Mathematics
is the square root of what number?
The square root of a number is the number which, when squared - multiplied by itself - yields that number as its result. Therefore, is the square root of
Example Question #84 : Fractions
Define an operation on the real numbers as follows:
Which of the following is an undefined quantity?
; since the divisor in a division expression cannot be equal to 0, it cannot hold that
, or
.
In other words, is undefined if and only if
.
The only choice in which this holds is .
Example Question #972 : Hspt Mathematics
Which of the following is the square root of 0.36?
The square root of 0.36 is therefore the square root of . The square root of a fraction whose numerator and denominator are both perfect squares can be found as follows:
Example Question #973 : Hspt Mathematics
Solve:
To multiple fractions, you just multiply the numerators together and the denominators together.
This gives you
as a numerator
and
as a denominator.
Your final answer would be .
Example Question #381 : Concepts
Which of the following is true of ?
Since ,
The correct choice is
.
Example Question #92 : Fractions
Which of the following is the greatest number?
,
.
The correct response is .
Example Question #382 : Concepts
Solve this problem:
To multiple fractions, you just have to multiple across.
First multiple the numerators
.
Then do the same for the denominators
.
This means the final answer after simplifying is
.
Example Question #94 : Fractions
To divide a fraction, multiply by it's multiplicative inverse, or reciprocal.
The multiplicative inverse or the reciprocal is for the fraction that comes after the division sign. The division sign will then change to a multiplication sign.
The multiplicative inverse or the reciprocal of is
.
Reduce to simplest form by dividing the numerator and the denominator by the Greatest Common Factor of 4 and 24, which is 4.
Example Question #93 : Fractions
To divide a fraction, multiply by it's multiplicative inverse, or reciprocal.
The multiplicative inverse or the reciprocal is for the fraction that comes after the division sign. The division sign will then change to a multiplication sign.
The multiplicative inverse or the reciprocal of is
.
Reduce to simplest form by dividing the numerator and the denominator by the Greatest Common Factor of 3 and 24, which is 3.
Example Question #96 : Fractions
To divide fractions, take the multiplicative inverse or reciprocal of the fraction that comes after the division sign and then change the division sign to a multiplication sign and multiply.
The multiplicative inverse of .
(A negative times a positive is a negative.)
Reduce to simplest form by dividing the numerator and the denominator by the Greatest Common Factor of 30 and 72, which is 6.
