When multiplying numbers in scientific notation what do you do with the exponent?
Add them
Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
How does multiplying 2 fractions differ from adding 2 fractions?

How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
How do you sum two fractions?
Make the demoninators (bottom numbers) the same by multiplying the top and bottom of one (or both) fractions, then add them as you would with integers.

When multiplying variables with the same base what do you do with the exponents?
You add them.

When multiplying a number exponents that are squared do you add or multiply?
If the base numbers or variables are the same, you add the exponents.
How do you add fractions with the same denominator with whole numbers?
First you add the fractions then add the whole numbers I'd you can you can reduce the fractions bye multiplying Hope you have fun!😺🐆💙💎💖🐾

When subtracting variables with exponents do you add or subtract the exponenets?
You cannot ad or subtract variables with different exponents: the exponents must be the same. The coefficients are added or subtracted and the exponent of the answer is the common exponent. (The rules are similar to those for the denominators of fractions.)Thus 2x^2 + 5x^3 cannot be combined into a single term.while 2x^2 + 5x^2 = (2+5)*x^2 = 7x^2

How do you combine same variables with different powers?
If the numbers are being multipled or divided then you add or subtract the exponent values, respectively.
What is x2 multiplied by 2x?
X2 * 2X= 2X3======multiply coefficients and add exponents ( all variables have a 1 as implied exponent )
When multiplying 2 or more variables with exponents what do you do with the exponents?
You add the exponents- x^2*x^6=x^8
