Front

What is scientific notation?

Back

A way of expressing numbers that are too large or too small to be conveniently written in decimal form, using powers of ten.

Front

How do you subtract numbers in scientific notation?

Back

Align the exponents, convert to the same base if necessary, and then subtract the coefficients.

Front

What is the formula for finding the greatest common factor (GCF)?

Back

The GCF of two or more numbers is the largest number that divides all of them without leaving a remainder.

Front

What is the rule for dividing exponents with the same base?

Back

Subtract the exponents: a^m / a^n = a^(m-n).

Front

What does it mean for an expression to be undefined?

Back

An expression is undefined when it involves division by zero or other operations that do not yield a valid result.

Front

What is the GCF of 7 and 11?

Back

1, since 7 and 11 are both prime numbers.

Front

How do you simplify the expression y^8/y^6?

Back

By subtracting the exponents: y^(8-6) = y^2.

Front

What is the value of x that makes the expression 5/(3x+1) undefined?

Back

x = -1/3, because it makes the denominator zero.

Front

What is the difference between a prime number and a composite number?

Back

A prime number has exactly two distinct positive divisors: 1 and itself. A composite number has more than two positive divisors.

Front

What is the purpose of using exponents in mathematics?

Back

Exponents are used to represent repeated multiplication of a number by itself.
