Question

Answer... The question in ... Simplify using the laws of exponents

Answer 1

Answer:

9/49

Step-by-step explanation:

(3/7 * 3/7*-1 * -1) is the answer after cutting

Answer 2

Step-by-step explanation:

ANSWER:-

Solving this first,

$( {{(\frac{3}{7} )}^{ - 2}})^{ - 3}$

${( \frac{3}{7} )}^{6}$

Now solving the second one,

${( \frac{ - 9}{49} })^{2}$

$= {( \frac{3}{7} ) }^{2 \times 2 }$

${ (\frac{3}{7}) }^{4}$

Dividing we know that the exponents subtract:-

So equation stands as

${ (\frac{3}{7}) }^{6 - 4}$

$= { (\frac{3}{7} )}^{2}$

9/49 is the answer.

Things to Note:-

• Dividing same bases , exponents subtract
• Multiplying same bases, exponents add
• Adding same, nothing happens
• Subtracting same bases nothing happens
