Question

c)(105-x):2⁵=3⁰+1

Answer 1

\(\left(105-x\right)\div2^5=3^0+1\)

\(\left(105-x\right)\div2^5=2\)

\(\left(105-x\right)=2\times2^5\)

\(105-x=2^6\)

\(x=105-64\)

x=41

Answer 2

c) (105 - x):32 = 2

105 - x             = 2.32

105 - x             = 64

         x             = 105 - 64

Vậy x = 41.

Answer 3

\(\left(105-x\right):2^5=0+1\)

\(105-x=1.2^5\)

\(x=105-32\)

\(x=73\)
