The quotient rule for exponents states that bm bn=_______, b≠0 . When dividing exponential expressions with the same nonzero b

wariber [46]

Answer:

The quotient rule for exponents states that $b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, subtract the exponents.

Step-by-step explanation:

Some rules to solve exponents are:

$x^{0}=1$
$(x^{m})^{n}=x^{mn}$
$x^{-n}=\frac{1}{x^{n}}$
$x^{m}\cdot x^{n}=x^{m+n}$
$\frac{x^{m}}{x^{n}}=x^{m-n}$

The quotient rule for exponents states that:

$b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, subtract the exponents.

Please help!!!!! I will give first answer brainliest.

zloy xaker [14]

a) +17 -9 = +8 . . . a profit of $8

b) +9 -5 = +4 . . . a rise of 4 cm

c) -6 -4 = -10 . . . a drop of 10 °C

_____

Each integer has a sign chosen with respect to some reference direction. We usually choose a rise or increase or profit to be the positive direction, so a drop or decrease or loss is then represented by a negative number.
