Question

Someone solve this and explain how 0.033 + (1.6 × 10-3)

Answer 1

`0.033 + (1.6*10-3)=13.033.\\ \\0.033 + (1.6*10^(-3) )=0.0346.`

Explanation:

Solution assuming that the parenthesis operation is: (1.6*10-3)

1. Write the expression.

`0.033 + (1.6*10-3)`

2. Remember PEMDAS.

Check the attached image.

This is an useful tool to know that operation to solve first.

3. Solve the parenthesis.

Since the parenthesis is the priority according to PEMDAS, let's start by solving what's inside of the parenthesis.

So, now that we are looking inside the parenthesis, the operation that goes first, according to PEMDAS, should be multiplication. So let's multiply!

Is this case we need to multiply 1.6 x 10. Result is the following:

`0.033 + (16-3)`

After that, solve the subtraction in order to clear the parenthesis.

`0.033 +13`

4. Complete by adding.

`13.033`

5. Express the final answer.

`0.033 + (1.6*10-3)=13.033`.

Solution assuming that the parenthesis operation is: (
`1.6*10^(-3)`)

1. Write the expression.

`0.033 + (1.6*10^(-3) )`

2. Rewrite and apply PEMDAS.

`0.033 + (1.6*(1)/(10^(3) ) )\\ \\0.033 + (1.6*(1)/(1000 ) )\\ \\0.033 + ((1.6)/(1000 ) )\\ \\0.033 + (0.0016)\\ \\0.0346`

Answer 2

0.0346

Explanation:

`\sf 10^(-3) = (1)/(10^3)= (1)/(1000)\\\\\\1.6*10^(-3)=(1.6)/(1000)\\`

= 0.0016

0.033 + 0.0016 = 0.0346

`= 3.46 * 10^(-2)`
