Question

evaluate the following:-

Answer 1

Answer:

Answer is 1

Step-by-step explanation:

since

3√64 . ( 5√32)^-2

3√4^3 . ( 5√2^5)^2

this gives us

4 . (2)^-2

now we know that if a^-n = (1 / a ) ^n

using this we get,

4 . (1 / 2)^2

4 . ( 1 / 4)

= 1

Answer 2

Hey there!

How u r doing well?

$given \: here \\ \\ \sqrt[3]{64} \times \sqrt[5]{32} {}^{ - 2} \\ \\ { {4}^{3} }^{ \frac{1}{3} } \times { {2}^{5} }^{ \frac{1}{5} } {}^{( - 2)} \\ \\ 4 \times {2}^{ - 2} \\ \\ 4 \times \frac{1}{ {2}^{2} } = 1$

Hope this helps u !
