Simplify the following expression. A.49 B.1/14 C.1/49 D.14

Anna35 [415]

Answer:

Step-by-step explanation:

Using the rules of exponents

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Hence

$7^{-5/6-7/6}$ = $7^{-\frac{12}{6} }$ = $7^{-2}$ , then

$7^{-2}$ = $\frac{1}{7^{2} }$ = $\frac{1}{49}$ → C

Why must you flip the inequality symbol when you divide by a negative number?

MariettaO [177]

That's a good question. When comparing negative numbers the lower one has a greater 'number part ( without the sign)' then the higher one.

For example -4 and -10:- 10 > 4 but -4 > -10.
