A negative sign before the number makes the whole expression negative. Think of taking the absolute value of the original number when you take the even root.

Calculate the power of large base integers and real numbers.

You can also calculate numbers to the power of large exponents less thannegative exponents, and real numbers or decimals for exponents.

For larger exponents try the Large Exponents Calculator For instructional purposes the solution is expanded when the base x and exponent n are small enough to fit on the screen.

Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or negative single digit integer less than 7 and greater than For example, 3 to the power of 4: Note that and -4 2 result in different answers: If you enter a negative value for x, such as -4, this calculator assumes -4 n.

For example, -4 2 means that -4 is to be raised to the second power. On the other hand, represents the additive inverse of Note that in this case the answer is the same for both and -3 3 however they are still calculated differently.

For 0 raised to the 0 power the answer is 1 however this is considered a definition and not an actual calculation.A Q&A with the author of a new book about how and why market forces have risen in public education.

Write the answer with positive exponents. Assume all variables represent positive numbers. Simplify the expression. Write the answer with positive exponents. Assume all variables represent positive numbers. (x 2 z) 1/4 /x-1/2 z 1/2. Math Math Help Math Expression Math Problem Math Help For College/5.

After completing this tutorial, you should be able to: Use the definition of exponents. Simplify exponential expressions involving multiplying like bases, zero as an exponent, dividing like bases, negative exponents, raising a base to two exponents, raising a product to an exponent and raising a .

To make a negative exponent positive, move the base and its exponent to the opposite location in the fraction (reciprocation). That is, a-n = 1/a n and 1/a-n = a n.. Using the laws of exponents, we can prove the above by the following.

That is, give the 15 an exponent of 1: Remove the parentheses on top by distributing exponents.

That is, by multiplying each exponent inside the parentheses by the exponent outside the parentheses on the right: Next we make each factor with a negative exponent have a positive exponent by bringing from numerator to .

Exponents are an essential part of basic math and appear on almost every high school exam and college entrance exam. Tips and Shortcuts Common Exponents Tests with Exponents Practice Questions Answer Key Tutorials.
