Mult

div

baseically, x is the base, and m and n are bases
you can only use this property if bases are same
baseically
multiply means add powers
divide means subtract bottom power from top
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
Answer:
b =21
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 + b^2 = 29^1
400 + b^2 =841
Subtract 400 from each side
b^2 = 441
Take the square root of each side
sqrt(b^2) = sqrt(441)
b =21
