Express 0.003259 in standard form correct to two significant figures

explain please

5.9 x 10^-5

Step-by-step explanation:

Move the point to the right . The power of the exponent becomes negative because we’re moving the point from left to right. The opposite is the case if we move the point to the left .

To two significant figures, move the point until you have just two figures left. So

5.9 x 10^-5 is the answer

3.3×10^-3

Step-by-step explanation:

0.003259 in standard form

When you see a standard form questions like this,you have to be patient

You will have to count the zeros backward

How many zeros are in front of the 3,that's two right

That means you take the decimal to the back of 3,that means the decimal is jumping three numbers

Since you are counting backward, that will be negative

So we have,

3.259×10^-3

Now to two significant figures

You will round up the 5 behind the 2 to 1 and add to the 2

Making 3,

So we have

3.3×10^-3

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
