Which Expression Has A Base With An Exponent Of 4

Which Expression Has a Base with an Exponent of 4?

In mathematics, exponents are used to represent repeated multiplication of the same number. When a number is raised to a power of 4, it means that the number is multiplied by itself four times. For example, 2^4 = 2 x 2 x 2 x 2 = 16.

There are many different expressions that can have a base with an exponent of 4. Some common examples include:

  • 4^4 = 256
  • (2^2)^4 = 256
  • (3^2)^2 = 81
  • (-2)^4 = 16

How to Identify Expressions with a Base of 4

There are a few different ways to identify expressions that have a base of 4. One way is to look for numbers that are raised to the power of 4. Another way is to look for expressions that are multiplied by themselves four times.

Conclusion

Expressions that have a base with an exponent of 4 are common in mathematics. They can be used to represent a variety of different values, and they can be simplified using the laws of exponents.

Expression with a Base with an Exponent of 4

An expression with a base raised to the fourth power is known as a quartic expression. It takes the general form:

ax4 + bx3 + cx2 + dx + e

where:

  • a, b, c, d, and e are real numbers
  • a ≠ 0
  • x is the variable

Properties of Quartic Expressions

  • The degree of a quartic expression is 4.
  • The x-intercepts of a quartic expression are the solutions to the equation ax4 + bx3 + cx2 + dx + e = 0.
  • The y-intercept of a quartic expression is the value of e.
  • The graph of a quartic expression is a parabola that can open up or down, depending on the sign of a.
