Question

Can someone help me out on this ♡​

Answer 1

Step-by-step explanation:

Actually, the diagram showned in the picture gave you some hints.

Moving every one block to the left indicates 10 times the value of the symbol than the previous one.

For instance,

`1\text{ km}=10^1\text{ hm}=10^2\text{ dam}=10^3\text{ m}`

Take the first question as example, since "k" is 9 blocks from the left of mu (u),

`1 \text{ kg}=10^9 \text{ }\mu\text{g}`

`\text{So }.000078\text{ kg}=.000078*10^9 \text{ }\mu\text{g}=7.8*10^(-5)*10^9 \text{ }\mu\text{g}=7.8* 10^4\text{ }\mu\text{g}`

Similarly,

`1 \text{ cL}=10^(-2) \text{ L}`

`\text{So }34800\text{ cL}=34800*10^(-2) \text{ L}=3.4800*10^(4)*10^(-2) \text{ L}=3.48* 10^2\text{ L}`

`1 \text{ Mm}=10^(3) \text{ km}`

`\text{So }.0283\text{ Mm}=.0283*10^(3) \text{ km}=2.83*10^(-2)*10^(3) \text{ km}=2.83* 10^1\text{ km}`
