Question

3√-16/128=
pls answer​

Answer 1

Answer:

8.875

Step-by-step explanation:

3×3-16÷128=8.875

Answer 2

Answer:

-1/2

Step-by-step explanation:

first of all we will do is make it in base and exponential form which is as follows :

16 = $2^{4}$

128 = $2^{7}$

So, now this is $2^{4}$/$2^{7}$ for -16/128 not for $\sqrt[3]{16/128}$ we will do it in further steps, then -16/128 = -1/$2^{3}$ here you would be thinking of why is it -1/$2^{3}$ as by the division law and negative law it changed and here is why - when ever there is '/' this sign it means division but we have '2' as same base so what we did was $2^{(7-4)}$ because of division law and we got $2^{3}$ and with negative law we did was with -16/128 we changed it in fraction form which is -1/$2^{3}$ and now this is clear..

Next step:

-16/128 = -1/$2^{3}$

$\sqrt[3]{16/128}$ = -1/2

here we did was we turned the cube into cube root because we transferred the cube to left hand side and whenever the side change the sign or the value becomes the opposite....

Hope it helps you...
