The first one is correct, but you can (and should) put it in simpler terms.

campbell_st · Answer

well if its



$$(\frac{3}{7})^2 = \frac{3^2}{7^2}$$

square the numerator and denominator

squaring a number means multiplying the number by its self

as an example 

$$5^2 = 5 \times 5 = 25$$

hope it helps

thankyou

campbell_st · Answer

the 2nd question seems to be incorrect as well its

$$3 \times (\frac{14}{4^2 - 3^2}) - 5$$

so start by simplifying the denominator of the fraction 

$$4^2 - 3^2 = ?$$

4^2 =16 and 3^2=9
