What is the slope of a line that is peroendicular to the line y equals 2x plus 5?
Perpendicular lines have a negative reciprocal slope. Slope of y=2x+5 is 2/1 negative reciprocal is (-1/2)
How do you Simplify x to the power of negative 2 and y to the power of 3?
It is y^3/x^2
What is perpendicular to y equals 6x plus -2?

What does 10 to the negative 73 power equal?
Any number x raised to a negative power -y is equivalent to the reciprocal of x raised to y. So, 10-73 would be the fraction 1 over the number 1 with 73 zeroes after it. A very small number indeed!
What is the slope of a line perpendicular to line y equals -2x plus 6?
The slope of the perpendicular to a line has a slope which is the negative reciprocal of the original line's slope.The negative reciprocal of x is -1/xSo in this case, where the slope is -2 the perpendicular line has the slope -1/(-2) or simply 1/2
What does 5 to negative 2 power equal?
it equals 1/25, or 0.04. A number to a negative power is the reciprocal of the number to that same positive power. x^(-y) = 1/(x^y)
What is the slope of a line that is peroendicular to the line y equals 2x plus 5?
Perpendicular lines have a negative reciprocal slope. Slope of y=2x+5 is 2/1 negative reciprocal is (-1/2)
What is 9 to the negative second power?
Whenever you see a negative exponent (the negative 2nd power), take the reciprocal of the answer (put one over it):x-y = 1/xySo:9-2 = 1/92 = 1/81 = 0.01234567901
What is -9 to the second power?
Whenever you see a negative exponent (the negative 2nd power), take the reciprocal of the answer (put one over it):x-y = 1/xySo:9-2 = 1/92 = 1/81 = 0.01234567901
What is a negative reciporcal?
it is -1 times one divided by the number that you are taking a reciprocal of. Negative reciprocals are very relevant because you have to take the negative reciprocal of the slope (m) in a function to get a perpendicular line. Ex.: y=2x+1 ┴ y=-1/2*x+1
Vocabulary word for 1 of 2 numbers whose product is one?
A reciprocal. x is the reciprocal of y means that x*y = 1 Also, if x is the reciprocal of y then y is the reciprocal of x.
How do you Simplify x to the power of negative 2 and y to the power of 3?
It is y^3/x^2
What is the reciprocal of a negative exponent when the exponent is a fraction?
The reciprocal of a^(-x/y) is 1/a^(x/y). The fact that the exponent is a fraction makes no difference.
What is perpendicular to y equals 6x plus -2?

How do you solve a math problem with a negative exponent?
Positive exponents: y squared, which is written as "y with a small raised 2", means "y to the power 2" , and that is y multiplied by y (Notice that we have used the y twice.) 5 to the power 3 is written as "5 with a small raised 3", and it means "five times five times five" which is 125. (Notice that we have used the 5 three times. Similarly 10 to the power 6 is written as "10 with a small raised 6", which means "10 x 10 x 10 x 10 x 10 x 10" and is 1,000,000. (Notice that the number 10 has been used 6 times. When we write the above examples, the 2 and the 3 and the 6 are positive numbers (but we don't use the positive sign.) They are positive exponents. Negative exponents: 10 to the power negative 2 which is written as "the number 10 with a small raised negative 2" means "the reciprocal of 10 to the power 2", which is "the reciprocal of 10 squared". Now the reciprocal of a number is 1 divided by that number, so the reciprocal of 10 is one over ten which is one tenth, and the reciprocal of 10 squared is 1 divided by 10 squared, which is 1 over 100, one hundredth. Similarly y to the power minus 4 would be 1 divided by y times y times y times y. And 6 to the power minus 3 would be 1 over 6 x 6 x 6; that's 1 divided by 216. Of course if you have a decent hand-held calculator you will find the way to solve a mathematical problem containing exponents from the instruction booklet.. You can also tackle such problems with the "scientific" calculator to be found on most computers. Use the word "calculator" in "search". That brings up a simple calculator. Then click on "View" followed by "scientific" and you then have a very powerful calculator which will deal with lots of scientific calculations. (Saves brainpower!)
