Question

Why what number should we multiply 2 raised to the power -5 so that the product is equal to 2 ​

Answer 1

Answer:

64

Step-by-step explanation:

(2^(-5)) × x = 2

x = 2 ÷ (2^(-5))

x = 2 × (2^5)

x = 2^6

x = 64

Answer 2

Answer:

Let the required number be K,

Given, Product of K and 2^( - 5 ) is equal to 2^( - 1 )

=> 2^( - 5 ) × k = 2^( - 1 )

\begin{gathered} = > K = \frac{ {2}^{ - 1} }{ {2}^{ - 5} } \\ \\ \\ = > K = {2}^{ - 1 - ( - 5)} \\ \\ \\ = > K = {2}^{ - 1 + 5} \\ \\ \\ = > K = {2}^{4} \end{gathered}

=>K=

2

−5

2

−1

=>K=2

−1−(−5)

=>K=2

−1+5

=>K=2

4

Hence, Required number is 2⁴
