Question

3 √ − 64/125 × √ 49/16

Answer 1

Answer:

-7/5

Step-by-step explanation:

4*4*4 = 4^3 = 64

5*5*5 = 5^3 = 125

7*7 = 7^2 = 49

4*4 = 4^2 = 16

Therefore $\sqrt[3]{-64/125}$ = - 4/5

and $\sqrt{49/16}$ = 7/4

Hence the answer is - 7/5

Answer 2

Answer:

4×4×4 = 4³ = 64

5×5×55 = 5³ = 125

7×7 = 7² = 49

4×4 = 4² = 16

Therefore \sqrt[3]{-64/125}3−64/125 = - 4/5

and \sqrt{49/16}49/16 = 7/4

Hence the answer is - 7/5
