12 hours ago Nov 26, 2012 . Exponents, powers and bases The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied. For example, “6 to the 5th power” may be written as “65.” Here, the base number is 6 and the exponent is 5.

Frequently Asked Questions

  • What are the rules for using exponents?

    The product rule for exponents state that when two numbers share the same base, they can be combined into one number by keeping the base the same and adding the exponents together. All multiplication functions follow this rule, even simple ones like 2*2, where both 2s have an exponent of one.

  • How do you evaluate an exponent?

    Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 3 4 indicates that the base number 3 is used as a factor 4 times. To determine the value of 3 4, multiply 3*3*3*3 which would give the result 81. Exponents are written as a superscript number (e.g.

  • What is the exponent of log?

    A log is an exponent because the log function is the inverse of the exponential function. The inverse function undoes the effect of the original function. (I’m not a big fan of most uses the term “cancel” in math, but it does fit in this situation.)

  • What is an exponent sign?

    An exponent is a number or symbol, placed above and to the right of the expression to which it applies, that indicates the number of times the expression is used as a factor.The exponent x in ( a + b ) x {\displaystyle (a+b)^{x}} indicates ( a + b ) {\displaystyle (a+b)} multiplied by itself x times.

  • What is the simple power rule?

    The power rule in calculus is a fairly simple rule that helps you find the derivative of a variable raised to a power, such as: x^5, 2x^8, 3x^(-3) or 5x^(1/2). All you do is take the exponent, multiply it by the coefficient (the number in front of the x), and decrease the exponent by 1.

  • What's the power of a power rule?

    The formal definition of the Power Rule is stated as "The derivative of x to the nth power is equal to n times x to the n minus one power," when x is a monomial (a one-term expression) and n is a real number. In symbols it looks as follows: d/dx xn = nxn - 1.

  • What are the rules for solving exponents?

    The quotient rule is one of the exponent rules that makes it easy to divide two exponents, or powers, with the same base. The quotient rule says that when you are dividing x^m by x^n, you can simply subtract the two exponents (m-n) and keep the same base.
