How does exponents work? Is it ust multiplication...please help me i am in grade 7 math
It is multiplication and more.
For instance, a^2 is a times a
a^3 is a times a times a, or a cubed.
Now it gets a little more fun.
a^(1/2) is the sqrt(a)
a^(1/3) is the cubrt(a)
a^(4/3) is the cubrt of a^4
neat.
like 2>2 is 4 and 2>3 is 8 because the first time you multiply you multiply by the original number???am i right ...sorry if its confusing???
You're right.
But be sure you use the correct signs.
2^2 = 4
2^3 = 8
thank you Ms.Sue and BobPursley
You're welcome.
Exponents are a way to represent repeated multiplication. They help us simplify and solve problems involving large numbers. In math, an exponent is represented as a small superscript number placed to the right and above a base number.
When we have a number with an exponent, it means we need to multiply the base number by itself the number of times indicated by the exponent. For example, 2^3 means "2 raised to the power of 3" and indicates that we need to multiply 2 by itself three times: 2 x 2 x 2 = 8.
In the case of 2^3, the base number is 2, and the exponent is 3. The base number tells us which number to multiply, and the exponent tells us how many times to multiply it. The result is called the "power" of the base number.
Exponents can also be negative or fractions. A negative exponent is used to represent a reciprocal or the inverse of a number. For example, 2^-2 is equal to 1/(2^2) = 1/4 or 0.25.
Fractional exponents can be used to calculate roots. For example, 8^(1/3) equals the cube root of 8, which is 2.
To calculate exponents, you can use a calculator, or you can do it manually by multiplying the base number by itself repeatedly according to the exponent. As you progress in math, you will learn techniques to simplify expressions with exponents and solve more complex equations.
