Hey Mate!!

${( \frac{7}{4} )}^{5} \times {( \frac{4}{7} )}^{7} \\ = > {( \frac{4}{7} )}^{ - 5} \times {( \frac{4}{7} )}^{7} \\ = > {( \frac{4}{7} )}^{ - 5 + 7} \\ = > { (\frac{4}{7} )}^{ 2} \\ = > \frac{16}{49}$

Answer 2

Answer:

0.31179

Step-by-step explanation:

^ symbol means that multiply 7 for 5 times and 4 also will be multiply 5 times or power of 7 is 5 and power of 4 is 5:

=(7/4) ^ 5

= 7* 7 * 7 * 7 * 7 / 4 * 4 * 4 * 4 * 4

= 16,807 / 1,024

= 16.41 (taken upto 2 decimal)

= (4/7) ^ 7

= 4 * 4 * 4 * 4 * 4 * 4 * 4 / 7* 7 * 7 * 7 * 7 * 7 * 7

= 16,384 / 823,543

= 0.019

Now we will mutliply both the parts as stated in the question:

= 16.41 * 0.019

= 0.31179
