How do you solve powers?

First you raise the expressions in the parentheses to their powers. Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases). Example 3: Next is an example with negative exponents.

What does a little 3 next to a number mean?

3 × 3 × 3. = 27. Note: we write “3 Cubed” as 33. (the little 3 means the number appears three times in multiplying)

How do you solve big powers?

As with most problems in basic algebra, solving large exponents requires factoring. If you factor the exponent down until all the factors are prime numbers – a process called prime factorization – you can then apply the power rule of exponents to solve the problem.

How do you divide powers?

To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

What does 7 to the power of 3 mean?

72 = 7 • 7 = 49. You can read 72 as “seven squared.” This is because multiplying a number by itself is called “squaring a number.” Similarly, raising a number to a power of 3 is called “cubing the number.” You can read 73 as “seven cubed.”
