Just a few days ago, we completed our chapter about exponents. We are writing a blog post about what we learned in math. The reason we are writing this blog is because our teacher wants to see if bringing more technology in math will make it easier for us to learn.
What’s a power?
A power has two parts; the base and the exponent. The base is the number that is going to be multiplied by itself as many times as the exponent.
Repeated Multiplication: 5x5x5
Standard Form: 125
What’s a product of power?
It’s a power timed by a power. For example, 25 x 23. The exponent law for a product of power is to keep the base the same and add the exponents. So, 25 x 23, the base will stay 2 but you will add 5 and 3 (the exponents), which will equal to 28. But this rule only applies where you are multiplying the powers with the same bases.
What’s a quotient of power?
It’s a power divided by a power. A quotient of power looks like 25/23. The exponent law for the quotient of power is to keep the same base but subtract the exponents, but this rule only applies where you are dividing the powers with the same bases. So, according to this law 25/23 would equal to 22.
Any power with an exponent of zero equals to -1 or 1.
